# About This Calculator

A Complex Fraction (also called a composite fraction) is a fraction where the numerator, the denominator, or both contain one or more fractions.

To simplify a complex fraction, you treat the main fraction bar as a division symbol. Using the "Keep, Change, Flip" method, you keep the numerator fraction, change division to multiplication, and flip (invert) the denominator fraction.

How To Use
