Frequently Asked Questions

How do you multiply fractions?

Multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator, then simplify using GCD.

How do you convert an improper fraction to a mixed number?

Divide the numerator by the denominator. The quotient becomes the whole number, and the remainder becomes the new numerator over the original denominator.
