which is 1/2

[tex]\bf \cfrac{~~\frac{3}{5}+\left( -\frac{1}{4} \right)~~}{\frac{7}{10}}\implies \cfrac{~~\frac{3}{5}-\frac{1}{4}~~}{\frac{7}{10}}\implies \cfrac{~~\frac{(4)3-(5)1}{20}~~}{\frac{7}{10}}\implies \cfrac{~~\frac{7}{20}~~}{\frac{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}[/tex]
