When adding 2/3 + 4/5 , what step must be completed first? A) Finding the least common denominator.
B) Reducing the fractions.
C) Adding the numerators, but keeping the denominators.
D) Adding the denominators, but keeping the numerators.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
