Answer
-$\frac{1}{5}$
Work Step by Step
$\frac{\frac{3}{5}-\frac{7}{10}}{\frac{1}{2}}$
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
-$\frac{1}{5}$
