Answer 2

I think you are confused with operations on fractions. So, I am doing step by step.

Explanation :

product of −317 and −12=−317×−12=−31×−17×2=3114.

sum of −135 and 127=(−135)+(127)

=(−13×75×7)+(12×57×5)

=(−9135)+(6035)

=(135)(−91+60)=−3135.

Dividing the sum of -13/5 and 12/7 by the product of -31/7 and -1/2

⟹−31353114=−31×1435×31=−1435=−25
