Question

Using appropriate properties find

$-\frac{2}{3}\times \frac{3}{5}+\frac{5}{2}-\frac{3}{5}\times \frac{1}{6}$

Answer 1

$\frac{-2}{3}\times \frac{3}{5}+\frac{5}{2}-\frac{3}{5}\times \frac{1}{6}$

$=\frac{-2}{5}+\frac{5}{2}-\frac{1}{5}\times \frac{1}{2}$

$=\frac{-2}{5}+\frac{5}{2}-\frac{1}{10}$

$=\frac{-4+25-1}{10}$

$=\frac{20}{10}=2$
