To add fractions, the denominators must be equal. Complete the following steps to add two fractions.
1.
Build each fraction so that both denominators are equal.
2.
Add the numerators of the fractions.
3.
The denominators will be the denominator of the built-up fractions.
4.

Example:
Calculate .
Solution:
The denominators are the same, so you can skip step 1. The denominator of the answer will be 5. Add the numerators for the numerator in the answer. 3 + 1 = 4. The answer is . This answer is already reduced, so you can skip step 4.

Check:
You can check the answer with your calculator. Calculate 3 divided by 5, calculate 1 divided by 5, and add the results. Now divide 4 by 5. Both answers should be the same. If you are correct, the answers are the same (equivalent) and you have successfully added two fractions.
