​

Answer 1

Step-by-step explanation:

$\frac{ - 2}{5} + \frac{2}{7} \div 2 \\ \frac{ - 2 \times 7}{5 \times 7} + \frac{2 \times 5}{7 \times 5} \times \frac{1}{2} \\ \frac{ - 14}{35} + \frac{10}{35} \times \frac{1}{2} \\ \frac{ - 4}{35} \times \frac{1}{2} \\ \frac{ - 4}{70} \\ \frac{ - 2}{35} \\ \\ so \: answer \: is \: \frac{ - 2}{35}$
