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 -$\frac{3}{4}$
