Question

Solve:
$\frac{5}{2}-\frac{3}{5}\times \frac{7}{2}+\frac{3}{5}\times \left(\frac{-2}{3}\right)$

Answer 1

Now,

$\frac{5}{2}-\frac{3}{5}\times \frac{7}{2}+\frac{3}{5}\times \left(\frac{-2}{3}\right)$

$=\frac{5}{2}-\frac{21}{10}-\frac{2}{5}$

$=\frac{25-21}{10}-\frac{2}{5}$

$=\frac{4}{10}-\frac{2}{5}$

$=\frac{2}{5}-\frac{2}{5}$

$=0$.
