Answer 1

Answer:

$Here, we \: have \: the \: sum \: of \: two \: rational \: number \: = \: \frac{ - 18}{21};one \: of \: the \: number \: = \frac{ - 3}{7}.$

$= > The \: other \: number \: = Sum - (one \: of \: the \: number)$

$\\ = > \frac{ - 18}{21} - ( \frac{ - 3}{7} ) = \frac{ - 18}{21} + (additive \: inverse \: of \: \frac{ - 3}{7} )$

$= > \frac{ - 18}{21} + \frac{3}{7} = \frac{ - 18}{21} + \frac{3 \times 3}{7 \times 3}$

$= > \frac{ - 18}{21} + \frac{9}{21} = \frac{ - 18 + 9}{21} = \frac{ - 9}{21} = \frac{ - 3}{7}$

I hope this will help you dear..

Always stay safe and stay healthy..

Answer 2

$\huge \color{indigo}Answer$

x = -9/21

Step-by-step explanation:

Given :-

The sum of two numbers is -18/21 .

One number = -3/7

☆ Let the second number be x.

ATQ,

x + (-3/7) = -18/21

x = -18/21 + 3/7

Taking LCM on RHS side,

LCM (21,7) = 21

x = -18/21 + 9/21

x = -9/21 or -3/7

hope it helps !
