Question

9/15+(+3/10-2/5-1/6)

Answer 1

$\frac{3}{5} +(\frac{3}{10}-\frac{2}{5}-\frac{1}{6}) =\frac{3}{5} +(\frac{3.3-2.6-1.5}{30}) =\frac{3}{5} +(\frac{9-12-5}{30}) =\frac{3}{5} +(\frac{-8}{30})=\frac{3}{5} -\frac{4}{15}$

$\frac{3}{5} -\frac{4}{15}=\frac{3.3-4.1}{15}=\frac{9-4}{15}=\frac{5}{15}=\frac{1}{3}$
