**Fractions Calculator** will perform basic arithmetic operations with fractions and mixed numbers.

Use this fraction calculator for adding, subtracting, multiplying and dividing fractions.

To **add fractions** containing unlike quantities (e.g. quarters and thirds), it is necessary to convert all amounts to like quantities. It is easy to work out the chosen type of fraction to convert to; simply multiply together the two denominators (bottom number) of each fraction.

.

Least common multiple denominators lcm(8, 6)=24.

The process for **subtracting fractions** is, in essence, the same as that of adding them: find a common denominator, and change each fraction to an equivalent fraction with the chosen common denominator.

.

Least common multiple denominators lcm(16, 20)=80.

To **multiply fractions**, multiply the numerators and multiply the denominators.

.

To **divide a fraction** by a whole number, you may either divide the numerator by the number, if it goes evenly into the numerator, or multiply the denominator by the number.
