Question

The sum of two rational numbers is 4/5 , if one of them is − 4/7 , find the other

Answer 1

Answer:

x + (-4/7) =4 /5

x - 4/7= 4/5

x = 4/5 +4/7

x= (4×7+4×5)/ 7×5

x = (28+20)/ 35

x= 48/35

Answer 2

• Let the other rational number be x.

☀️ It's given, the sum of two rational numbers is 4/5 and one of them is − 4/7.

According to The Question:-

↠ x +(-4/7) = 4/5

↠ x - 4/7 = 4/5

↠ x = 4/5 +4/7

↠ x = (28+20)/35

↠ x = 48/35

☀️ Therefore , the other rational number will be 48/35.
