Answer 1

Step-by-step explanation:

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