Adding dissimilar fractions involves finding a common denominator for the fractions before adding them together. This common denominator is the least common multiple of the denominators of the fractions being added. Once the fractions have the same denominator, you can add the numerators together while keeping the denominator the same. Finally, simplify the resulting fraction if possible by reducing it to its simplest form.

Dissimilar fractions have different denominators and their lowest common denominator must be found in order to add them up.
Fractions with different denominators.
Dissimilar fractions have different denominators as in the following examples 1/2, 3/5 and 7/8
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.
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.
Fractions that are not equivalent are dissimilar fractions * * * * * The term is used more commonly to refer to fractions whose denominators are different.
