The additive inverse of

$\frac{ - 5}{ - 7} = \frac{5}{7} \: is \: - \frac{5}{7}$

The additive inverse of

$\frac{ - 3}{10} \: is \: \frac{3}{10}$

So the required answer is

$= \frac{3}{10} - ( - \frac{5}{7} ) = \frac{3}{10} + \frac{5}{7} = \frac{71}{70}$

Step-by-step explanation:

-5/-7 = -5/7

-3/10 = 3/10

(-5/7)-(3/10)

lcm= 70

-50/70 - 21/70

= -71/70
