Question

Write a pair of fractions whose sum is 7 /11 and difference is 2/ 11​

Answer 1

Let the first fraction be x

Then second fraction= 7/11 -x

Since,

1st fraction-2nd Fraction = 2/11

》x-(7/11-x) = 2/11

》x-7/11+x= 2/11

》2x= 2/11+7/11

》2x= 9/11

Therefore, x = 9/22

7/11-x = 7/11-9/22

14-9/22

5/22

Therefore

First Fraction = 9/22

Second Fraction = 5/22
