Answer:hope you understand
Step-by-step explanation:
Sum= 13/5 + -12/7 = same denominator by l.c.m
= 91/35 + -60/35 = 31/35
Product = -31/7 × 1/-2 = -31/-14 = minus and minus should be cancelled = 31/14
Now,divide the sum and the product
31/35 ÷ 31/14 = 31/35 × 14/31 = cancel 31 by 31 and 14 and 35 = 2/5
Ans: 2/5
