Answer 1

sum of -13/5 and 12/7
-91+60/35=-31/35
product = -31/7 ×1/-2 =31/14
Now -31/35÷31/14 =-31/35 ×14/31 =-5/2 Ans

Answer 2

Given:

Four fractions -13/5, 12/7 , -31/7, 1/-2.

To Find:

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

Solution:

Sum of (-13/5) and 12/7

=(-13/5)+(12/7)

=((-13×7)+(12×5))/35

=(-91+60)/35

=(-31)/35

Product of (-31/7 )and (1/-2)

=(-31/7)×(-1/2)

=31/14

Now,

Divide (-31)/35 by 31/14

=-(31/35)÷31/14

=-(14/35)

=-2/5

Hence, the answer is (-2/5).
