Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Addition:

3/13 + 5/26 + 7/39

(Take L.C.M of denominators)

L.C.M = 78

Now multiply 13×6 & 3×6 so that is = 18/78

Now multiply 26×3 & 5×3 so that is = 15/78

Now multiply 39×2 & 7×2 so that is = 14/78

18/78 + 15/78 + 14/78 = 47/78

The Answer is 47/78

Subtraction:

47/78 - 47/78 = 0

Hence the answer is 0
