Answer 5

$16 times frac{1}{4} - (8 times frac{2}{5} + 3 times frac{3}{10} ) = \ frac{65}{4} - ( frac{42}{5} + frac{33}{10} ) = \ frac{65}{4} - ( frac{84 + 33}{10} ) = \ frac{65}{4} - frac{117}{10} = \ frac{65 times 5}{20} - frac{117 times 2}{20} = \ frac{325}{20} - frac{234}{20} = \ frac{325 - 234}{20} = frac{91}{20} = 4 times frac{11}{20}$
