Question
By what number should $\frac{-8}{15}$ be multiplied to get 24?
✓
Answer
The required number $=24\div\Big(\frac{-8}{15}\Big)$
$=24\times\frac{15}{-8}$
$=24\times\frac{15\times(-1)}{-8\times(-1)}$
$=24\times\frac{(-15)}{-8}$
$=3\times(-15)$
$=-45$
$=24\times\frac{15}{-8}$
$=24\times\frac{15\times(-1)}{-8\times(-1)}$
$=24\times\frac{(-15)}{-8}$
$=3\times(-15)$
$=-45$
