Solution

Solution:

We know that additive inverse of a rational number,
$\frac{a}{b} i s (\frac{- a}{b}), s u c h t h a t \frac{a}{b} + (\frac{- a}{b}) = 0$

a) Additive inverse of $\frac{2}{8}$ is $\frac{- 2}{8}$ .

b) Additive inverse of $\frac{2}{- 9}$ is $\frac{2}{9}$ .

c) Additive inverse of $\frac{- 19}{- 6}$ is $\frac{- 19}{6}$ .
