Adding Fractions Examples

Adding Fractions Calculator for math help.

Adding fractions is usually the first concept to learn when working with fractions. Take a look at some of these examples and use the fraction calculator to help you with your understanding.

 

How to Add Fractions

Example: For adding the fractions 1/3 and 1/5, you must first modify the fractions so that the denominators are the same. For these two fractions, the result would be 5/15 and 3/15.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
5 + 3 = 8.

The sum is 8/15

1/4 plus 1/3

Example: For adding the fractions 1/4 and 1/3, you must first modify the fractions so that the denominators are the same. For these two fractions, the result would be 3/12 and 4/12.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
3 + 4 = 7.

The sum is 7/12

1/3 plus 1/3

Example: For adding the fractions 1/3 and 1/3, you must first modify the fractions so that the denominators are the same, which they already are. For these two fractions, the result remains as 1/3 and 1/3.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
1 + 1 = 2.

The sum is 2/3

3/4 plus 1/3

Example: For adding the fractions 3/4 and 1/3, you must first modify the fractions so that the denominators are the same. For these two fractions, the result would be 9/12 and 4/12.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
9 + 4 = 13.

The sum is 13/12 which is also written as 11/12

3/4 plus 1/4

Example: For adding the fractions 3/4 and 1/4, you must first modify the fractions so that the denominators are the same, which they already are. For these two fractions, the result remains as 3/4 and 1/4.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
3 + 1 = 4.

The sum is 4/4, which is actually just 1.

2/3 plus 2/3

Example: For adding the fractions 2/3 and 2/3, you must first modify the fractions so that the denominators are the same, which they already are. For these two fractions, the result remains as 2/3 and 2/3.

The second step is to add the numerators of the two fractions to find the numerator of the answer,
2 + 2 = 4.

The sum is 4/3 which is also written as 11/3
