Question

Find the value
$\frac{2}{5}\times \left[\frac{-3}{7}\right]+\frac{1}{14}\times \frac{2}{5}-\frac{1}{4}$

Answer 1

We have,

$\frac{2}{5}\times \left[\frac{-3}{7}\right]+\frac{1}{14}\times \frac{2}{5}-\frac{1}{4}$

$\Rightarrow \frac{-6}{35}+\frac{1}{35}-\frac{1}{4}$

$\Rightarrow \frac{-6+1}{35}-\frac{1}{4}$

$\Rightarrow \frac{-5}{35}-\frac{1}{4}$

$\Rightarrow \frac{-20-35}{140}$

$\Rightarrow \frac{-55}{140}$

$\Rightarrow \frac{-11}{28}$

Hence, this is the answer.
