# Fractions Calculator

## Calculator Use

Use this fraction calculator for adding, subtracting, multiplying and dividing fractions. Answers are provided as simplified fractions in lowest terms or as mixed numbers in reduced form. Input proper or improper fractions, select the math operation and click Calculate.

You can also add, subtract, multiply or divide negative fractions. Insert a negative (minus) sign before the numerator (top number) for each fraction that is negative. For example if one of your fractions is -16/20 just insert a "-" before the "16" and proceed to enter all other numerators and denominators. Choose the math operation and click Calculate.

To calculate with mixed numbers (whole numbers and fractions) use the Mixed Numbers Calculator.
