Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.
Multiply both parts of each fraction by the denominator of the other fraction, if the denominators are different. For example, if you are adding 1/3 and 2/5, multiply both 1 and 3 by 5, making the fraction 5/15. Then multiply both 2 and 5 by 3 (the denominator of the other fraction), making the fraction 6/15.

For example, if you are adding 1/3 and 2/5, multiply both 1 and 3 by 5, making the fraction 5/15. Then multiply both 2 and 5 by 3 (the denominator of the other fraction), making the fraction 6/15.Make the previous step easier if one of the denominators is a multiple of the other. For example, if you are adding 1/2 and 3/12, 12 is a multiple of 2 (2 x 6 = 12). In this case, leave 3/12 as is. Multiply both parts of 1/2 by 6 so that the denominator will be 12, making the fraction 6/12.
