Best ResponseYou've already chosen the best response.1When we have fractions with different denominators, we cannot add or subtract straightforwardly. We first have to convert each to a common denominator. For example, if we had 1/3 + 1/4 we would convert both fractions such that each had a denominator of 12 1/3 = 4/12 1/4 = 3/12 1/3 + 1/4 = 4/12 + 3/12 = 7/12 Another way of asking the question is: what is a common multiple of 3 and 4? In this case, 12 is. So we convert each fraction so it has a denominator of 12, then add them. The same reasoning is true for your problem. What is a common multiple of 2 and 5?
