Question

Q1. The sum of two rational numbers is -4 if one of them is -11/5
Find the other.
​

Answer 1

Answer:

-9/5

Step-by-step explanation:

Let the unknown no. be 'x'

Given,

One of the no. is -11/5

Sum of the no.s is -4

∴ x + (-11/5) = -4

Taking LCM,

5x - 11

---------  =  -4

   5

5x - 11 = -20

     5x = -20 + 11

     5x = -9

      x = -9/5

Hence, the other no. is -9/5
