Question 14

Which of the fractions given below, when added to $$ \frac{5}{7} $$, gives 1?

Solution

Let the fraction be 1/x

According to the question,

(1/x) + (5/7) = 1

1/x = 1 - (5/7)

1/x = 2/7 (or) 6/21 (if '3' is multiplied to numerator and denominator)

Hence, option B is the correct answer.
