Question

Write the additive inverse of each of the following.
(i) $\frac{2}{8}$ (ii) $\frac{-5}{9}$ (iii) $\frac{-6}{-5}$ (iv) $\frac{2}{-9}$ (v) $\frac{19}{-6}$

Answer 1

Additive inverse of $\frac{a}{b}$ is $-\frac{a}{b}$, since $\frac{a}{b}+(-\frac{a}{b})=0$

In the same manner:

(i)

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

(ii)

Additive inverse of $\frac{-5}{9}$ is $\frac{5}{9}$

(iii)

Additive inverse of $\frac{-6}{-5}$ is $\frac{-6}{5}$

(iv)

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

(v)

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