Answer 1

Answer:

45/31 is the answer.

Step-by-step explanation:

To find the sum of -13/5 and 12/7.

LCM of 5 and 7 is 35.

-13/5×7/7=-91/35

12/7×5/5=60/35

By adding 91/35 and 60/35 we get:

-91/35+60/35= -31/35

To find the product of -13/7 and -1/2

LCM of 7 and 2 is 14.

-13/7×2/2= -26/14

-1/2×7/7= -7/14

By multiplying -26/14 and -7/14

= -26/14×-7/14

= 182/14

Now, to divide 182/14 and -31/35.

LCM of 14 and 35 is 70.

182/14×5/5=910/70

-31/35×2/2= -62/70

Now, we can divide each other easily.

=910/70÷-62/70

=910/70×-70/62

= -45/31

100% guarantee right answer.
