Question

By what number should $\frac{-8}{15}$ be multiplied to get 24?

Answer 1

$\begin{array}{l}\\ \text{Let the required number be}\mathit{\text{x.}}\\ x\times \left(\frac{-8}{15}\right)=24\\ \begin{array}{l}x=\text{24}÷\frac{-8}{15}\\ =\sout{2}{\sout{4}}^3\times \left(\frac{15}{-{\sout{8}}_1}\right)\\ =\frac{45\times (-1)}{-1\times (-1)}\\ =-45\end{array}\end{array}$
