Simplify Fractions Calculator

Reduce a fraction to its lowest terms. The calculator finds the highest common factor of the top and bottom, divides both by it, and shows the result as a mixed number when it is top-heavy. If the fraction will not reduce, it says so and explains why nothing divides both parts.
