​

Answer 1

Answer:

$\frac{2}{5} - \frac{3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5} \\ = \frac{2}{5} - \frac{3}{7} - \frac{1}{14} - \frac{9}{35} \\ = l \: c \: m \: of \: 5 \: 7 \: 14 \: and \: 35 \: is \: 70 \\ = \frac{28 - 30 - 5 - 18}{70} \\ = \frac{28 - 53}{70} \\ = \frac{ - 25}{70} \\ = \frac{ - 5}{14} ans$
