Question 37 Exercise 1.1

Write the additive inverse of each of the following.

$(i) \frac{2}{8} (iv) \frac{2}{-9} (ii) \frac{-5}{9} (iii) \frac{-6}{-5} (v) \frac{19}{-6}$

Answer:

$\text { (i) } \frac{2}{8}$

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

$\text { (ii) } \frac{-5}{9}$

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

$\text { (iii) } \frac{-6}{-5}=\frac{6}{5}$

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

$\text { (iv) } \frac{2}{-9}=\frac{-2}{9}$

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

$\text { (v) } \frac{19}{-6}=\frac{-19}{6}$

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