Question

Sum of two rational number is 3 /5 if one of them is minus 2 /7 find the other

Answer 1

Answer:

Sum of two rational number is 3 /5

now, (-2/7) is one of the rational number.

let the other rational number is a.

then, a+(-2/7) =(3/5)

Or, a= (3/5) +(2/7)

or, a=(21+10) /35

or, a=31/35

the required rational number is 31/35
