Question

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

Answer 1

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

As per the question,  

(-13/5 + 12/7) / (-13/7 * -1/2)

-13/5 + 12/7 = (-91 + 60)/35 = -31/35

-13/7 * -1/2 = 13/14

Now, you need to divide -31/35 with 13/14

(-31/35) / (13/14)

-31/35 * 14/13

-31/5 * 2/13

-62/65

Hence the outcome of (-13/5 + 12/7) / (-13/7 * -1/2) = -62/65
