11/15 has the denominator 15, just like i worked out, and the numerator 11. i didn't think it could be b because you have to do the same thing to the numerator as you do to the denominator, so you couldn't have 3/15 as an answer.

11/15 is the answer and because the calculation includes fractions with different denominators, we have to convert them to have the common denominator which would be fifteenths so 1/3 equals 5/15 and 2/5 equals 6/15 so 5/15 plus 6/15 equals 11/15.
