Question

the sum of two rational numbers is - 4/5.if one of them is - 11/20. find the other.

Answer 1

let one no. be x

ATQ

x+ (-11/20) = -4/5

x= -4/5+11/20

x = (-16+11)/20

x = -5/20

x = -1/4

Answer 2

Answer:

Given that one number is -11/20, we will consume that the second number is x.

$x + ( \frac { - 11}{20} ) = - \frac{4}{5}$

$x = - \frac{4}{5} + \frac{11}{20}$

$x = \frac{1}{4}$

The second number is -¼.

Hence solved ✅✅✅
