Question

$\frac{2}{5} \times \frac{ - 3 }{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}$
​

Answer 1

The value of the expression is $-\frac{1}{2}$.

Step-by-step explanation:

The expression is:

$\frac{2}{5}\times\frac{-3}{7}-\frac{1}{14}-\frac{3}{7}\times \frac{3}{5}$

Compute the value of the expression as follows:

$\frac{2}{5}\times\frac{-3}{7}-\frac{1}{14}-\frac{3}{7}\times \frac{3}{5}=(\frac{2}{5}\times\frac{-3}{7})-\frac{1}{14}-(\frac{3}{7}\times \frac{3}{5})$

$=\frac{-6}{35}-\frac{1}{14}-\frac{9}{35}$

$=\frac{-12-5-18}{70}$

$=\frac{-35}{70}$

$=-\frac{1}{2}$

Thus, the value of the expression is $-\frac{1}{2}$.
