-$\frac{1}{5}$
$\frac{\frac{3}{5}-\frac{7}{10}}{\frac{1}{2}}$ First multiply $\frac{3}{5}$ by $\frac{2}{2}$ so it has a denominator of 10 $\frac{\frac{6}{10}-\frac{7}{10}}{\frac{1}{2}}$ Then subtract $\frac{-\frac{1}{10}}{\frac{1}{2}}$ Then change the division to multiplication of the reciprocal of the denominator -$\frac{1}{10}$$\times$$\frac{2}{1}$ Then multiply -$\frac{2}{10}$ Then reduce by 2 -$\frac{1}{5}$
