Question

Find the multiplicative inverse of:
(i) $\frac{-3}{4}$
(ii) $\frac{11}{4}.$

Answer 1

$$\begin{gathered} \left(\mathrm{i}\right)\mathrm{Multiplicative}\mathrm{inverse}\mathrm{of}\frac{-3}{4}\mathrm{is}\frac{4}{-3},\mathrm{i}.\mathrm{e}.,\frac{-4}{3}. \\ \left(\mathrm{ii}\right)\mathrm{Multiplicative}\mathrm{inverse}\mathrm{of}\frac{11}{4}\mathrm{is}\frac{4}{11}. \end{gathered}$$
