Write each of the following as a rational number with positive denominator.

(i) $\frac{12}{-17}$
(ii) $\frac{1}{-2}$
(iii) $\frac{-8}{-19}$
(iv) $\frac{11}{-6}$

Answer 1

(i) $\frac{12\times (-1)}{(-17)\times (-1)}=\frac{-12}{17}$

(ii) $\frac{1\times (-1)}{(-2)\times (-1)}=\frac{-1}{2}$

(iii) $\frac{-8}{-19}=\frac{-8\times (-1)}{(-19)\times (-1)}=\frac{8}{19}$

(iv) $\frac{11\times (-1)}{-6\times (-1)}=\frac{-11}{6}$
