Answer 1

So the sum of

$\frac{ - 5}{7} + \frac{ - 8}{3}$

$\frac{ - 15 - 56}{21}$

$\frac{ - 71}{21}$

$\frac{5}{2} + \frac{ - 11}{12}$

$\frac{30 - 11}{12}$

$\frac{19}{12}$

So

$\frac{ - 71}{21} + \frac{19}{12}$

$\frac{399 - 852}{252}$

$\frac{ - 453}{252}$

Answer 2

Explanation :-

(5/2 + -11/12) - ( -5/7 + -8/3)

= (19/12) - (-71/21)

= 417/84 Ans.
