By what number should $\frac{-3}{4}$ multiplied in order to produce $\frac{2}{3}$?
To do:
We have to find the number that should be multiplied by $\frac{-3}{4}$ so that the product is $\frac{2}{3}$.
Solution:
Let the number that should be multiplied by $\frac{-3}{4}$ so that the product is $\frac{2}{3}$ be $x$.
This implies,
$\frac{-3}{4}\times x=\frac{2}{3}$
$x=\frac{2}{3}\div\frac{-3}{4}$
$x=\frac{2}{3}\times\frac{4}{-3}$
$x=\frac{2\times4}{3\times-3}$
$x=\frac{8}{-9}$
$x=\frac{-8}{9}$
Therefore, the other number is $\frac{-8}{9}$.
