Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Fill in the blanks:
(i) Additive inverse of $\frac{-5}{-12}=\dots \dots ...$
(ii) $\frac{-5}{-12}+$ its additive inverse $=\dots \dots ...$
(iii) If $\frac{a}{b}$ is additive inverse of $\frac{-c}{d}$, then $\frac{-c}{d}$ is additive inverse of ........... .

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Also so $\frac{a}{b}+\frac{(-c)}{d}-\frac{(-c)}{d}+\frac{a}{b}=\dots \dots \dots .$
(i) Additive inverse of $\frac{-5}{-12}=-\frac{5}{12}$.
(ii) $\frac{-5}{-12}+$ its additive inverse $=\frac{-5}{-15}+(-\frac{5}{15})$ $r0$.
(iii) If $\frac{a}{b}$ is additive inverse of $\frac{-c}{d}$, then $\frac{-c}{d}$ is additive inverse of $\frac{a}{b}$.
Also so $\frac{a}{b}+\frac{(-c)}{d}-\frac{(-c)}{d}+\frac{a}{b}=0$.
