Question

The sum of two numbers is -3/7 . If one rational number is 2/21, then the other rational number is

Answer 1

Answer:

let the other number is x

so,

2/21 +x= -3/7

=> x= -3/7-2/21

=> x=(-9-2)/21

=> x= -11/21

so the other rational number is -11/21

Answer 2

Step-by-step explanation:

Let the number be x

A/Q,

$\frac{ 2}{21} + x = \frac{ - 3}{7}$

$x = \frac{ - 3}{7} - \frac{2}{21}$

$x = \frac{ -9 - 2}{21}$

$x = \frac{ - 11}{21}$
