Rational Numbers Class 8 Worksheet With Answers Pdf Question 1. Pick up the rational numbers from the following numbers. \(\frac { 6 }{ 7 }\), \(\frac { -1 }{ 2 }\), 0, \(\frac { 1 }{ 0 }\), \(\frac { 100 }{ 0 }\) Solution: Since rational numbers are in the form of \(\frac { a }{ b }\) where b ≠ 0. Only \(\frac { 6 }{ 7 }\), \(\frac { -1 }{ 2 }\) and 0 are the rational numbers.

Find the reciprocal of the following rational numbers: (a) \(\frac { -3 }{ 4 }\) (b) 0 (c) \(\frac { 6 }{ 11 }\) (d) \(\frac { 5 }{ -9 }\) Solution: (a) Reciprocal of \(\frac { -3 }{ 4 }\) is \(\frac { -4 }{ 3 }\) (b) Reciprocal of 0, i.e. \(\frac { 1 }{ 0 }\) is not defined. (c) Reciprocal of \(\frac { 6 }{ 11 }\) is \(\frac { 11 }{ 6 }\) (d) Reciprocal of \(\frac { 5 }{ -9 }\) = \(\frac { -9 }{ 5 }\)
Class 8 Maths Chapter 1 Extra Questions Question 3. Write two such rational numbers whose multiplicative inverse is same as they are. Solution: Reciprocal of 1 = \(\frac { 1 }{ 1 }\) = 1 Reciprocal of -1 = \(\frac { 1 }{ -1 }\) = -1 Hence, the required rational numbers are -1 and 1.
Rational Numbers Class 8 Extra Questions Question 4. What properties, the following expressions show? (i) \(\frac { 2 }{ 3 } +\frac { 4 }{ 5 } =\frac { 4 }{ 5 } +\frac { 2 }{ 3 }\) (ii) \(\frac { 1 }{ 3 } \times \frac { 2 }{ 3 } =\frac { 2 }{ 3 } \times \frac { 1 }{ 3 }\) Solution: (i) \(\frac { 2 }{ 3 } +\frac { 4 }{ 5 } =\frac { 4 }{ 5 } +\frac { 2 }{ 3 }\) shows the commutative property of addition of rational numbers. (ii) \(\frac { 1 }{ 3 } \times \frac { 2 }{ 3 } =\frac { 2 }{ 3 } \times \frac { 1 }{ 3 }\) shows the commutative property of multiplication of rational numbers.

Question 23. One-third of a group of people are men. If the number of women is 200 more than the men, find the total number of people. Solution: Number of men in the group = \(\frac { 1 }{ 3 }\) of the group Number of women = 1 – \(\frac { 1 }{ 3 }\) = \(\frac { 2 }{ 3 }\) Difference between the number of men and women = \(\frac { 2 }{ 3 }\) – \(\frac { 1 }{ 3 }\) = \(\frac { 1 }{ 3 }\) If difference is \(\frac { 1 }{ 3 }\), then total number of people = 1 If difference is 200, then total number of people = 200 ÷ \(\frac { 1 }{ 3 }\) = 200 × 3 = 600 Hence, the total number of people = 600
