Answer 2

Hello Mate!

We will use formulae ( r + s ) / 2,

$( \frac{ - 3}{7} + \frac{2}{5} ) \div 2 \\ ( \frac{ - 15 + 14}{35} ) \times \frac{1}{2} = \frac{ - 1}{70}$

In , -3/7 and -1/70 we have

$( \frac{ - 3}{7} + \frac{ - 1}{70} ) \div 2 \\ \frac{ - 31}{140}$

In, -3/7 and - 31/140

$( \frac{ - 3}{7} + \frac{ - 31}{140} ) \div 2 \\ \frac{ - 60 + ( - 31)}{28 0} = \frac{ - 91}{280}$

In, -1/70 and 2/5 we have

$( \frac{ - 1}{70} + \frac{2}{5} ) \div 2 \\ \frac{27}{140}$
In 27/140 and 2/5 we have

$( \frac{27}{140} + \frac{2}{5} ) \div 2 \\ \frac{27 + 56}{280} = \frac{83}{280}$

Hope it helps☺!
