Question

The sum of two rational number is -8. If one of them is -15 over 7. Find the other.

Answer 1

One of the two numbers = -15/7

Let the other number = m

Sum = -8

According to Question:

m + (-15/7) = -8

m - 15/7 = - 8

m = -8 + 15/7

m = (-56+15)/7

m = -41/7

Hence, the other number is -41/7

Answer 2

Let other number = m

One number = -15/7

Sum of numbers = -8

Therefore,

m + (-15/7) = -8

m - 15/7 = - 8

m = -8 + 15/7

m = -41/7

Hence, the other number is -41/7
