Question

the sum of two rational numbers is - 8 . If one of the number is - 15 by 7 find the other rational number​

Answer 1

Let the other no. be x.

x + (-15/7) = -8

x = -8 + 15/7

x = (-56 + 15)/7

x = -41/7

Therefore,the other rational number is -41/7.

Answer 2

Answer:

The other rational number =  $\frac{-41}{7}$

Step-by-step explanation:

Given,

Sum of two rational numbers = -8

One number is $\frac{-15}{7}$

To find,

The second rational number

Solution:

Let 'x' be the required rational numbers

Then, the two rational numbers are 'x' and $\frac{-15}{7}$

Since the sum of these two rational numbers is -8. we have

x +  $\frac{-15}{7}$ = -8

x = -8 -( $\frac{-15}{7}$)

x = -8 + $\frac{15}{7}$

x = $\frac{-56+15}{7}$

x = $\frac{-41}{7}$

∴ The other rational number =  $\frac{-41}{7}$
