Answer 2

Given: A fraction 5/7

To find: How much should be added to 5/7 to make it one whole

Solution: According to the given question,

We need to find a fraction which when added with 5/7 gives 1

To find such number we need to subtract 5/7 from 1

⇒ 1 - $\frac{5}{7}$

Taking L.C.M as 7, the common denominator will become 7

⇒ $\frac{7 - 5}{7}$ = $\frac{2}{7}$

Hence, 2/7 needs to be added to 5/7 to make one whole

Verification:

For verification, we need to check if addition of 5/7 and 2/7 gives 1

⇒ $\frac{5}{7} + \frac{2}{7}$ = $\frac{7}{7}$ = 1.

Hence, verified that 5/7 + 2/7 = 1
