Question

By what number should we multiply \[\frac{- 8}{13}\]

 so that the product may be 24?

Answer 1

\[\text{Let the number be x .} \]
\[ \therefore x \times \frac{- 8}{13} = 24\]
\[\text{or}\ x = 24 \div \frac{- 8}{13}\]
\[\text{or}\ x = 24 \times \frac{13}{- 8}\]
\[\text{or}\ x = - 39\]
\[\text{Thus, the number is - 39 .}\]
