The answer is 24/35 because you have to find what 5 and 7 go into which would be 35 so that would be the denominator so when trying to change the numerator you would have to times 7 by 5 to get the denominator of 35 so then times the numerator (2) by 5 to get the new numerator which would be ten then you would do 5x7 which would give the denominator of 35 so the numerator (2) would times by 7 to make 14 so then it would be 14/35 + 10/35 which would give the answer of 24/35
