Question

9. If each of the following pairs represents a pair of equivalent rational

numbers, find the values of x.
(i) 3/4 and 7/x
(ii) -5/6 and x/7

Answer 1

-35/6

Explanation:

We need to find the value of x , And the given pair of Rational numbers are equal.

Question (I) :-

→ 3/4 = 7/x

→ 7/x = 3/4

→ 1/x = 3/4 × 1/7

→ 1/x = 3/28

→ x = 28/3

Question (ii) :-

→ x/7 = -5/6

→ x = -5/6 × 7

→ x = -35/6

• Hence the value of x is -35/6 .
