Answer 2

$\sf\huge\bold{Answer:}$

Given :

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

To Find :

Solution of given term .

Solution :

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

Combining terms on basis of common terms,we get

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

Taking out common terms,we obtain

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

Simplifying further,

$= \frac{3}{35} ( - 5) - \frac{1}{14}$

On Multiplying terms,

$= \frac{ - 15}{35} - \frac{1}{14}$

Simplifying term by cutting

$= - \frac{3}{7} - \frac{1}{14}$

Taking LCM,

$= \frac{ - 3 \times 2 - 1}{14}$

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

$= \frac{ - 7}{14}$

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

So,

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