# Complex Fractions Calculator

## Calculator Use

A complex fraction is a fraction that contains another fraction. Use this Complex Fractions Calculator to do math and add, subtract, multiply and divide complex fractions. Fraction answers are provided in reduced form (lowest terms).

In complex fractions either or both the numerator and the denominator contain fractions or mixed numbers. A simple integer may also be part of the complex fraction, appearing in either the numerator or the denominator.

For addition and subtraction problems, the calculator converts mixed numbers to improper fractions, and then finds the least common denominator before proceeding with the math. For multiplication and division problems it is not necessary to find a common denominator, so the calculator simply follows standard rules of arithmetic with fractions.
