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.

You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
similar fraction is the same denominator and dissimilar fraction is cannot the same denominators
Make the fractions equivalent then subtract
Similar fractions have the same denominator, dissimilar ones don't.
1. change the dissimilar fractions to similar fractions by getting the L.C.D or the least common denominator. 2. add the whole numbers and write down the given denominator. 3. reduce the answer to lowest term if possible.
