Answer 2

`\cfrac{1}{4}b-\cfrac{1}{2}=\cfrac{2}{5}\implies \cfrac{b}{4}-\cfrac{1}{2}=\cfrac{2}{5}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{20}}{20\left( \cfrac{b}{4}-\cfrac{1}{2}\right)=20\left( \cfrac{2}{5} \right)}\implies 5b-10=8 \\\\\\ 5b=18\implies b=\cfrac{18}{5}\implies b=3(3)/(5)`
