Question:
By what number should $\frac{-3}{4}$ be multiplied in order to produce $\frac{2}{3} ?$
Solution:
Let the other number that should be multiplied with $\frac{-3}{4}$ to produce $\frac{2}{3}$ be $\mathrm{x}$.
$\therefore \mathrm{x} \times \frac{-3}{4}=\frac{2}{3}$
or $\mathrm{x}=\frac{2}{3} \div \frac{-3}{4}$
or $\mathrm{x}=\frac{2}{3} \times \frac{4}{-3}$
or $x=\frac{-8}{9}$
Thus, the number is $\frac{-8}{9}$.
