Answer:

27/28

Step-by-step explanation:

Given:- The given fraction is 2/7. Sum of two fractions is 5/4.

To Find:- We need to find the number which will be added to 2/7 so that the result is 5/4.

Solution:-

The given fraction is 2/7.

Here we need to find the number such that the sum of that number and 2/7 is 5/4.

We can find the number by subtracting 2/7 from 5/4.

Let the number be x.

According to question,

              2/7 + x = 5/4
