Answer 2

To add or subtract fractions, you need to have a common denominator. In this case, all the fractions already have the same denominator, which is 15. So, you can add and subtract them directly:

(7/15) + (4/15) + (13/15) - (9/15)

Now, add and subtract the numerators while keeping the common denominator:

(7 + 4 + 13 - 9) / 15

Combine the numerators:

(15) / 15

Now, simplify the fraction:

15/15 is equal to 1.

So, the result of the expression is:

1/1, which is just equal to 1.
