Answer
-$\frac{3}{4}$
Work Step by Step
$\frac{\frac{1}{4}-\frac{1}{2}}{\frac{1}{3}}$
First multiply $\frac{1}{2}$ by $\frac{2}{2}$ so it has a denominator of 4
$\frac{\frac{1}{4}-\frac{2}{4}}{\frac{1}{3}}$
Then subtract
$\frac{-\frac{1}{4}}{\frac{1}{3}}$
Then change the division to multiplication of the reciprocal of the denominator
-$\frac{1}{4}$$\times$$\frac{3}{1}$
Then multiply
-$\frac{3}{4}$
