Work Step by Step

$\dfrac{\dfrac{7}{10}-\dfrac{3}{5}}{\dfrac{1}{2}}$ Evaluate the substraction indicated in the numerator: $\dfrac{\dfrac{7}{10}-\dfrac{3}{5}}{\dfrac{1}{2}}=\dfrac{\dfrac{7-3(2)}{10}}{\dfrac{1}{2}}=\dfrac{\dfrac{7-6}{10}}{\dfrac{1}{2}}=\dfrac{\dfrac{1}{10}}{\dfrac{1}{2}}=...$ Evaluate the division and simplify if possible: $...=\dfrac{1}{10}\div\dfrac{1}{2}=\dfrac{2}{10}=\dfrac{1}{5}$
