Question

By what number should we multiply $\frac{-8}{13}$ so that the product may be 24?

Answer 1

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{number}be\mathrm{x}. \\ \therefore \mathrm{x}\times \frac{-8}{13}=24 \\ \mathrm{or}\mathrm{x}=24÷\frac{-8}{13} \\ \mathrm{or}\mathrm{x}=24\times \frac{13}{-8} \\ \mathrm{or}x=-39 \\ Thus,\mathrm{the}\mathrm{number}\mathrm{is}-39. \end{gathered}$$
