Answer 1

For given the sum of two rational number is

21 /4

Where one of the rational number is

7/5

Hence the other rational number is =

21/4

−

7/5

=

21/4−15

=−

21/11

HOPE IT HELPS ❤️

Answer 2

Solution:

Given, the sum of two rational numbers is $\frac{-2}{3}$.

One of the number is $\frac{-8}{15}$

Let the other number be "$x$"

So, $\frac{-8}{15} + x = \frac{-2}{3}$

$\frac{-8}{15} - \frac{-2}{3} = -x$

Here LCM of 15 and 3 is 15. So,

$\frac{-8}{15} + \frac{2(5)}{3(5)} = -x$

$\frac{-8+10}{15} = -x$

$-x =$ $\frac{2}{15}$

$x=\frac{-2}{15}$

Verification:

$\frac{-8}{15} +\frac{-2}{15}$

$\frac{-8-2}{15}$

$\frac{-10}{15}$

Dividing numerator and denominator by $5$.

$\frac{-2}{3}$

Therefore, the other rational number is $\frac{-2}{15}$.
