Answer:

-78/35

Explanation:

2/5+3/7+(-6/5)+(-13/7)

First we will solve 2/5+3/7

Making the denominator same

LCm of 5 and 7 = 35

We know that lcm divides by the denominator than the answer get multiplied by numerator

So, 5÷ 35 = 7 and 7÷ 35= 5

Than 7×2 and 5× 3

=14/35 + 15/35 = 29/35

Now, We will solve (-6/5)+(-13/7)

making denominator same

=LCM = 35

=5÷ 35 = 7 and 7÷ 35= 5

= 7×6 = 42 and 5×13= 65

So, (-42/35)+(-65/35)= - 107/35

29/35+(-107/35)

= -78/35
