Question

Answer please with full explanation​

Answer 1

$\frac{2}{5} \times ( - \frac{3}{7}) - \frac{1}{9} \times \frac{6}{7} + \frac{1}{14} \times \frac{2}{5}$

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

$= - \frac{6}{35} - \frac{2}{21} + \frac{1}{35}$

$= \frac{ - 18 - 10 + 3}{105}$

$= \frac{ - 28 + 3}{105}$

$= - \frac{25 }{105}$

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