$\huge\bold\red{Answer}$

$\tt \implies \: let \: the \: other \: rational \: \\ \tt no. \: be \: x. \\ \\ \tt given \\ \tt \implies \: x + \frac{ -8}{9} = \frac{ - 2}{5} \\ \\ \tt \: now \\ \tt \implies \: x = \frac{ - 2}{5} + \frac{8}{9} \\ \tt \implies \: x = \frac{ - 18 + 40}{45} \\ \tt \implies \: x = \frac{22}{45}$

Hence, the rational number is 22/45.

I Hope It Helps You✌️

Answer 2

-8/9 + x = -2/5

x = -2/5 + 8/9

LCM = 45

So, -18/45 + 40/45

= 22/45
