\bf \cfrac{~~(3)/(5)+\left( -(1)/(4) \right)~~}{(7)/(10)}\implies \cfrac{~~(3)/(5)-(1)/(4)~~}{(7)/(10)}\implies \cfrac{~~((4)3-(5)1)/(20)~~}{(7)/(10)}\implies \cfrac{~~(7)/(20)~~}{(7)/(10)} \\\\\\ \cfrac{7}{20}\cdot \cfrac{10}{7}\implies \cfrac{7}{7}\cdot \cfrac{10}{20}\implies 1\cdot \cfrac{1}{2}\implies \cfrac{1}{2}

First you would remove the parenthesis, subtract the fractions, simplify the fraction, then receive your answer.

which is 1/2
