Multiplying Mixed Fractions
("Mixed Fractions" are also called "Mixed Numbers")
To multiply Mixed Fractions :
- convert to Improper Fractions
- Multiply the Fractions
- convert the result back to Mixed Fractions
Example: What is 1 3 8 × 3 ?
Think of Pizzas.
First, convert the mixed fraction (1 3 8 ) to an improper fraction ( 11 8 ):
Now multiply that by 3:
And, lastly, convert to a mixed fraction (only because the original fraction was in that form):
And this is what it looks like in one line:
1 3 8 × 3 = 11 8 × 3 1 = 33 8 = 4 1 8
Another Example: What is 1 1 2 × 2 1 5 ?
Do the steps from above:
Step, by step it is:
Convert Mixed to Improper Fractions:
1 1 2 = 2 2 + 1 2 = 3 2
2 1 5 = 10 5 + 1 5 = 11 5
Multiply the fractions (multiply the top numbers, multiply bottom numbers):
3 2 × 11 5 = 3 × 11 2 × 5 = 33 10
Convert to a mixed number
33 10 = 3 3 10
If you are clever you can do it all in one line like this:
1 1 2 × 2 1 5 = 3 2 × 11 5 = 33 10 = 3 3 10
One More Example: What is 3 1 4 × 3 1 3 ?
3 1 4 = 13 4
3 1 3 = 10 3
13 4 × 10 3 = 130 12
Convert to a mixed number:
130 12 = 10 10 12
And simplify :
10 10 12 = 10 5 6
Here it is in one line:
3 1 4 × 3 1 3 = 13 4 × 10 3 = 130 12 = 10 10 12 = 10 5 6
This One Has Negatives: What is −1 5 9 × −2 1 7 ?
1 5 9 = 9 9 + 5 9 = 14 9 2 1 7 = 14 7 + 1 7 = 15 7
Then multiply the Improper Fractions (note that negative times negative gives positive ) :
−14 9 × −15 7 = −14 × −15 9 × 7 = 210 63
We can simplify now. Here we use two steps, first by 7 (21 and 63 are both multiples of 7), then again by 3. But it could be done in one step by dividing by 21:
210 63 = 30 9 = 10 3
Finally convert to a Mixed Fraction (because that was the style of the question):
10 3 = (9+1) 3 = 9 3 + 1 3 = 3 1 3

- Solve application problems that require multiplication of fractions or mixed numbers.
Introduction
Just as you add, subtract, multiply, and divide when working with whole numbers, you also use these operations when working with fractions. There are many times when it is necessary to multiply fractions and mixed numbers . For example, this recipe will make 4 crumb piecrusts:
5 cups graham crackers
8 tablespoons sugar
\(\ 1 \frac{1}{2}\) cups melted butter
\(\ \frac{1}{4}\) teaspoon vanilla
Suppose you only want to make 2 crumb piecrusts. You can multiply all the ingredients by \(\ \frac{1}{2}\), since only half of the number of piecrusts are needed. After learning how to multiply a fraction by another fraction, a whole number or a mixed number, you should be able to calculate the ingredients needed for 2 piecrusts.
Multiplying Fractions
When you multiply a fraction by a fraction, you are finding a “fraction of a fraction.” Suppose you have \(\ \frac{3}{4}\) of a candy bar and you want to find \(\ \frac{1}{2}\) of the \(\ \frac{3}{4}\):
By dividing each fourth in half, you can divide the candy bar into eighths.
Then, choose half of those to get \(\ \frac{3}{8}\).
In both of the above cases, to find the answer, you can multiply the numerators together and the denominators together.
Multiplying Two Fractions
\(\ \frac{a}{b} \cdot \frac{c}{d}=\frac{a \cdot c}{b \cdot d}=\frac{\text { product of the numerators }}{\text { product of the denominators }}\)
\(\ \frac{3}{4} \cdot \frac{1}{2}=\frac{3 \cdot 1}{4 \cdot 2}=\frac{3}{8}\)
Multiplying More Than Two Fractions
\(\ \frac{a}{b} \cdot \frac{c}{d} \cdot \frac{e}{f}=\frac{a \cdot c \cdot e}{b \cdot d \cdot f}\)
\(\ \frac{1}{3} \cdot \frac{2}{4} \cdot \frac{3}{5}=\frac{1 \cdot 2 \cdot 3}{3 \cdot 4 \cdot 5}=\frac{6}{60}\)
\(\ \frac{8}{15}\)
If the resulting product needs to be simplified to lowest terms, divide the numerator and denominator by common factors.
\(\ \frac{2}{3} \cdot \frac{1}{4}=\frac{1}{6}\)
You can also simplify the problem before multiplying, by dividing common factors.
You do not have to use the “simplify first” shortcut, but it could make your work easier because it keeps the numbers in the numerator and denominator smaller while you are working with them.
\(\ \frac{3}{4} \cdot \frac{1}{3}\) Multiply. Simplify the answer.
- \(\ \frac{3}{12}\)
- \(\ \frac{4}{7}\)
- \(\ \frac{1}{4}\)
- \(\ \frac{36}{144}\)
- Incorrect. \(\ \frac{3}{12}\) is an equivalent fraction to the correct answer \(\ \frac{1}{4}\), but it is not in lowest terms. You must divide numerator and denominator by the common factor 3. The correct answer is \(\ \frac{1}{4}\).
- Incorrect. You may have added numerators (3+1) and added denominators (4+3) instead of multiplying. The correct answer is \(\ \frac{1}{4}\).
- Correct. One way to find this answer is to multiply numerators and denominators, \(\ \frac{3 \cdot 1}{4 \cdot 3}=\frac{3}{12}\), then simplify: \(\ \frac{3 \div 3}{12 \div 3}=\frac{1}{4}\).
- Incorrect. You probably found a common denominator, multiplied correctly, but then forgot to simplify. Finding a common denominator is not necessary and makes the multiplication harder because you are working with greater than necessary numbers. The correct answer is \(\ \frac{1}{4}\).
Multiplying a Fraction by a Whole Number
When working with both fractions and whole numbers, it is useful to write the whole number as an improper fraction (a fraction where the numerator is greater than or equal to the denominator). All whole numbers can be written with a "1" in the denominator. For example: \(\ 2=\frac{2}{1}\), \(\ 5=\frac{5}{1}\), and \(\ 100=\frac{100}{1}\). Remember that the denominator tells how many parts there are in one whole, and the numerator tells how many parts you have.
Multiplying a Fraction and a Whole Number
\(\ a \cdot \frac{b}{c}=\frac{a}{1} \cdot \frac{b}{c}\)
\(\ 4 \cdot \frac{2}{3}=\frac{4}{1} \cdot \frac{2}{3}=\frac{8}{3}\)
Often when multiplying a whole number and a fraction, the resulting product will be an improper fraction. It is often desirable to write improper fractions as a mixed number for the final answer. You can simplify the fraction before or after rewriting it as a mixed number. See the examples below.
\(\ 7 \cdot \frac{3}{5}=4 \frac{1}{5}\)
\(\ 4 \cdot \frac{3}{4}=3\)
\(\ 3 \cdot \frac{5}{6}\) Multiply. Simplify the answer and write it as a mixed number.
- \(\ 1 \frac{1}{7}\)
- \(\ 2 \frac{1}{2}\)
- \(\ \frac{5}{2}\)
- \(\ \frac{8}{6}\)
- Incorrect. You may have added the numerators and added the denominators to get \(\ \frac{8}{7}\), which is the mixed number \(\ 1 \frac{1}{7}\). Make sure you multiply numerators and multiply denominators. Multiplying the two numbers gives you \(\ \frac{15}{6}\), and since \(\ 15 \div 6=2 \mathrm{R} 3\), the mixed number is \(\ 2 \frac{3}{6}\). The fractional part simplifies to \(\ \frac{1}{2}\). The correct answer is \(\ 2 \frac{1}{2}\).
- Correct. Multiplying the two numbers gives \(\ \frac{15}{6}\), and since \(\ 15 \div 6=2 \mathrm{R} 3\), the mixed number is \(\ 2 \frac{3}{6}\). The fractional part simplifies to \(\ \frac{1}{2}\).
- Incorrect. Multiplying the numerators and multiplying the denominators results in the improper fraction \(\ \frac{5}{2}\), but you need to express this as a mixed number. The correct answer is \(\ 2 \frac{1}{2}\).
- Incorrect. You may have added numerators and placed it over the denominator of 6. Make sure you multiply numerators and multiply denominators. Multiplying the two numbers gives \(\ \frac{15}{6}\), and since \(\ 15 \div 6=2 \mathrm{R} 3\), the mixed number is \(\ 2 \frac{3}{6}\). The fractional part simplifies to \(\ \frac{1}{2}\). The correct answer is \(\ 2 \frac{1}{2}\).
Multiplying Mixed Numbers
If you want to multiply two mixed numbers, or a fraction and a mixed number, you can again rewrite any mixed number as an improper fraction.
So, to multiply two mixed numbers, rewrite each as an improper fraction and then multiply as usual. Multiply numerators and multiply denominators and simplify. And, as before, when simplifying, if the answer comes out as an improper fraction, then convert the answer to a mixed number.
\(\ 2 \frac{1}{5} \cdot 4 \frac{1}{2}=9 \frac{9}{10}\)
\(\ \frac{1}{2} \cdot 3 \frac{1}{3}=1 \frac{2}{3}\)
As you saw earlier, sometimes it’s helpful to look for common factors in the numerator and denominator before you simplify the products.
\(\ 1 \frac{3}{5} \cdot 2 \frac{1}{4}=3 \frac{3}{5}\)
In the last example, the same answer would be found if you multiplied numerators and multiplied denominators without removing the common factor. However, you would get \(\ \frac{72}{20}\), and then you would need to simplify more to get your final answer.
\(\ 1 \frac{3}{5} \cdot 3 \frac{1}{3}\)
- \(\ \frac{80}{15}\)
- \(\ 5 \frac{5}{15}\)
- \(\ 4 \frac{14}{15}\)
- \(\ 5 \frac{1}{3}\)
- Incorrect. You probably wrote both mixed numbers as improper fractions correctly. You probably also correctly multiplied numerators and denominators. However, this improper fraction still needs to be rewritten as a mixed number and simplified. Dividing \(\ 80 \div 15=5\) with a remainder of 5 or \(\ 5 \frac{5}{15}\), then simplifying the fractional part, the correct answer is \(\ 5 \frac{1}{3}\).
- Incorrect. You probably wrote both mixed numbers as improper fractions correctly. You probably also correctly multiplied numerators and denominators, and wrote the answer as a mixed number. However, the mixed number is not in lowest terms. \(\ \frac{5}{15}\) can be simplified to \(\ \frac{1}{3}\) by dividing numerator and denominator by the common factor 5. The correct answer is \(\ 5 \frac{1}{3}\).
- Incorrect. This is the result of adding the two numbers. To multiply, rewrite each mixed number as an improper fraction: \(\ 1 \frac{3}{5}=\frac{8}{5}\) and \(\ 3 \frac{1}{3}=\frac{10}{3}\). Next, multiply numerators and multiply denominators: \(\ \frac{8}{5} \cdot \frac{10}{3}=\frac{80}{15}\). Then, write the resulting improper fraction as a mixed number: \(\ \frac{80}{15}=5 \frac{5}{15}\). Finally, simplify the fractional part by dividing both numerator and denominator by the common factor, 5. The correct answer is \(\ 5 \frac{1}{3}\).
- Correct. First, rewrite each mixed number as an improper fraction: \(\ 1 \frac{3}{5}=\frac{8}{5}\) and \(\ 3 \frac{1}{3}=\frac{10}{3}\). Next, multiply numerators and multiply denominators: \(\ \frac{8}{5} \cdot \frac{10}{3}=\frac{80}{15}\). Then write as a mixed fraction \(\ \frac{80}{15}=5 \frac{5}{15}\). Finally, simplify the fractional part by dividing both numerator and denominator by the common factor 5.
Solving Problems by Multiplying Fractions and Mixed Numbers
Now that you know how to multiply a fraction by another fraction, by a whole number, or by a mixed number, you can use this knowledge to solve problems that involve multiplication and fractional amounts. For example, you can now calculate the ingredients needed for the 2 crumb piecrusts.
The ingredients needed for 2 pie crusts are:
\(\ 2 \frac{1}{2}\) cups graham crackers
4 tablespoons sugar
\(\ \frac{3}{4}\) cup melted butter
\(\ \frac{1}{8}\) teaspoon vanilla
Often, a problem indicates that multiplication by a fraction is needed by using phrases like “half of,” “a third of,” or "\(\ \frac{3}{4}\) of."
The cost of a vacation is \(\ \$ 4,500\) and you are required to pay \(\ \frac{1}{5}\) of that amount when you reserve the trip. How much will you have to pay when you reserve the trip?
You will need to pay \(\ \$ 900\) when you reserve the trip.
Hours spent:
sleeping: 8 hours
attending school: 4 hours
eating: 2 hours
Neil bought a dozen (12) eggs. He used \(\ \frac{1}{3}\) of the eggs for breakfast. How many eggs are left?
- Correct. \(\ \frac{1}{3}\) of 12 is \(\ 4\left(\frac{1}{3} \cdot \frac{12}{1}=\frac{12}{3}=4\right)\), so he used 4 of the eggs. Because \(\ 12-4=8\), there are 8 eggs left.
- Incorrect. \(\ \frac{1}{3}\) of 12 is 4, but that gives how many eggs Neil used, not how many he had left. You need to subtract 4 from 12 to find the number of remaining eggs. The correct answer is 8.
- Incorrect. You may have incorrectly found \(\ \frac{1}{3}\) of 12 to be \(\ \text { 3. } \frac{1}{3}\) of 12 is 4, and then 12-4 is 8. The correct answer is 8.
- Incorrect. You need to find \(\ \frac{1}{3}\) of 12, which is 4. Then subtract 4 from 12 to get 8 remaining eggs.
You multiply two fractions by multiplying the numerators and multiplying the denominators. Often the resulting product will not be in lowest terms, so you must also simplify. If one or both fractions are whole numbers or mixed numbers, first rewrite each as an improper fraction. Then multiply as usual, and simplify.

Mixed numbers are numbers that have both a whole number part and a fractional part. They are commonly used to represent quantities that are not whole numbers, such as lengths, weights, or volumes. For example, 2 1/2 (two and one-half) is a mixed number because it contains a whole number (2) and a fraction (1/2).
Mixed numbers are a useful way to represent and compare quantities that are not exactly whole numbers. They help us understand the world around us better and make it easier to solve real-life problems involving fractions.
How to Multiply Mixed Numbers?
When it comes to multiplying mixed numbers, there are a few simple steps to follow:
- Convert the mixed numbers to improper fractions.
- Multiply the improper fractions.
- Simplify the result, if necessary.
- Convert the result back to a mixed number, if desired.
In the following sections, we will explore each of these steps in more detail and provide examples to help solidify your understanding.

Multiplying Two or More Mixed Numbers
To multiply two or more mixed numbers, first convert them to improper fractions. An improper fraction is a fraction where the numerator (top number) is greater than or equal to the denominator (bottom number). To convert a mixed number to an improper fraction, use the following formula:
Improper Fraction = (Whole Number × Denominator) + Numerator / Denominator
Once you have converted the mixed numbers to improper fractions, simply multiply the numerators and multiply the denominators. Finally, simplify the resulting fraction, if possible.
Multiplying a Mixed Number with Fraction
When multiplying a mixed number with a fraction, the process is very similar to multiplying two mixed numbers. First, convert the mixed number to an improper fraction. Then, multiply the improper fraction and the given fraction. As always, simplify the result if necessary.
Multiplying a Mixed Number by a Whole Number
Multiplying a mixed number by a whole number is a straightforward process. First, convert the mixed number to an improper fraction. Next, multiply the numerator of the improper fraction by the whole number, keeping the denominator unchanged. Finally, simplify the result and convert it back to a mixed number, if desired.

Can I use the same process for dividing mixed numbers?
- Yes, but you will need to multiply by the reciprocal of the second mixed number (or fraction) instead of directly multiplying. The overall process remains similar.

Mixed Numbers Multiplication Word Problems
Example 1. Sai spent 8 hours selling vegetables in the market. Murali sells for 1\(\frac {1}{ 4} \) times as many hours as Sai. How many hours did Murali sell vegetables in the market? Solution: Time is taken by Sai for selling the vegetables= 8 hours Murali sells vegetables =1 \(\frac {1}{ 4} \) × 8 =\(\frac {5}{ 4} \) × 8 =\(\frac {5}{ 4} \)× \(\frac {8}{ 1} \) =\(\frac {40}{ 4} \) =10 Therefore, Murali spent 10 hours selling vegetables in the market.
Example 2. On Doctor’s advice, Rajesh decided to walk every day. He walks \(\frac {4}{ 7} \) kilometers every day. How many kilometers did he walk in a week? Solution: Rajesh walk every day= \(\frac {4}{ 7} \) No. of kilometers Rajesh walk in a week=7 × \(\frac {4}{ 7} \) =4 km Therefore, Rajesh walks 4 km a week.
Example 3. The heaviest weight in the family of Sarath is 90 kg. Sarath’s weight is \(\frac {1}{ 3} \) of the heaviest weight. Find the weight of Sarath? Solution: The heaviest weight in the family = 90 kg Sarath weight= \(\frac {1}{ 3} \)× 90 =30 kg Hence, Sarath’s weight is 30 kg.
Example 4. Supriya is interested in singing and dancing. Supriya practices 28 hours a week with them. She takes \(\frac {1}{ 3} \) of the time for singing and \(\frac {1}{ 4} \) of the time for dancing. How many hours does she take for dancing? Solution: Total no. of hours Supriya practice every week= 28 Supriya takes time for singing=\(\frac {1}{ 3} \) Supriya takes time for dancing=\(\frac {1}{ 4} \) No. of hours she spends in dancing=\(\frac {1}{ 4} \)× 28 =7 Therefore, Supriya takes 7 hours for dancing.
Example 5. In an office, there are 2000 employees. Male employees are \(\frac {1}{ 4} \). Find the Female employees in the office? Solution: Total no. of employees in the office=2000 No. of male employees=\(\frac {1}{ 4} \) No. of female employees=1-\(\frac {1}{ 4} \)=\(\frac {3}{4} \) \(\frac {3}{ 4} \)× 2000=1500. Therefore, the total no. of female employees in the office is 1500.
Example 6. Games are conducted for the students in class X. \(\frac {3}{ 8} \) of the total no of students are in class X. \(\frac {1}{ 5} \) of the students in class X participate in games. What fraction of all the students participate in the games? Solution: No. of students in the class X= \(\frac {3}{ 8} \) No. of students participate in the games=\(\frac {1}{ 5} \) Fraction of all students participate in the games=\(\frac {3}{ 8} \) × \(\frac {1}{5} \)=\(\frac {3}{40} \) Therefore, the fraction of all the students participating in the exam is \(\frac {3}{40} \) .
Example 7. Jagadish planted a mango tree and guava tree in the garden. The guava tree is 3 \(\frac {1}{ 5} \) feet tall. The mango tree is 1 \(\frac {1}{ 3} \) as tall as the guava tree. How tall is the mango tree? Solution: The height of the guava tree=3 \(\frac {1}{5} \) The height of the mango tree =1\(\frac {1}{ 3} \) × 3 \(\frac {1}{ 5} \) =\(\frac {4}{ 3} \) × \(\frac {16}{ 5} \) =\(\frac {4 × 16}{ 3× 5} \) =\(\frac {64}{15} \) =4 \(\frac {4}{15} \) Therefore, the height of the mango tree is 4 \(\frac {4}{15} \).
Example 8. The cake needs 3 \(\frac {1}{2} \) cups of flour. Janci is baking 2 \(\frac {1}{ 2} \) cakes. How many cups of flour will she need? Solution: No. of cups of flour required for cake=3 \(\frac {1}{ 2} \) No. of cakes baking= 2 \(\frac {1}{ 2} \) No. of cups of flour required=2 \(\frac {1}{ 2} \) × 3 \(\frac {1}{ 2} \) =\(\frac {5}{ 2} \)× \(\frac {7}{ 2} \) =\(\frac {35}{ 4} \) =8 \(\frac {3}{ 4} \) Therefore, 8 \(\frac {3}{ 4} \) cups of flour required for baking 2 \(\frac {1}{ 2} \) cakes.
Example 9. Sirisha uses \(\frac {2}{5} \) liters of petrol in her Scooty for 1 km. Find how many liters of petrol Sirisha use to drive 1 \(\frac {3}{8} \) km? Solution: No. of liters of petrol for 1 km=\(\frac {2} {5} \) No. of liters of petrol used for 1 \(\frac {3}{ 8} \) km= 1 \(\frac {3}{ 8} \) × \(\frac {2} {5} \) =\(\frac {11} {8} \)× \(\frac {2} {5} \) =\(\frac {22} {40} \) =\(\frac {11} {10} \) Therefore, Sirisha uses \(\frac {11} {10} \) lt of petrol for 1 \(\frac {3} {8} \) km.
Example 10. A restaurant makes sweet lime juice on Friday and uses 3 \(\frac {1} {8} \) kg of sweet limes. As Saturday is a busy day, the restaurant plans to make 8 \(\frac {1} {9} \) as much as sweet lime juice. How many kg of Sweet lime juice is required?
