To multiply fractions, multiply the numerators and then multiply the denominators. The answer is a fraction with the product of the numerators being its numerator and the product of the denominators being its denominator. Reduce the answer to its lowest terms if necessary.

Example: How much is multiplied by ?

Sometimes, you may want to divide a numerator and a denominator by a common factor before you multiply the numerators and denominators. This is called Cancellation. Cancellation simplifies multiplication of fractions.

Example: How much is multiplied by ?
Since the denominator 3 in the first fraction is a factor of the numerator 9 in the second fraction, we can divide both 3 and 9 by 3 to get a new denominator 1 for the first fraction and a new numerator 3 for the second fraction. After this cancellation, multiplication of the two fractions becomes easier:
