If needed you simplify the fraction. Simplify your result if necessary.
Next you add the numerators together and put the result over that same denominator.
How to add fractions with like denominators. Using the above example we can define the following steps to add two or more fractions with the same denominator. The following steps will be useful to add fractions with the same denominators. To add fractions together when they have a common denominator you simply add all the numerators together and rewrite the sum over the original denominator.
To add two or more fractions that have the same denominators add the numerators and place the resulting sum over the common denominator. In the fractions 3 5 and 2 5 the numerators are 3 and 2. First you write down the same denominator.
When two or more more fractions with the same denominator are added take the denominator once. Adding fractions with like denominators can be done in 3 steps. In the fractions 3 8 5 8 and 17 8 the numerators are 3 5 and 17.
