Multiplying fractions

Proper fractions

Worked example

To multiply a proper fraction, multiply the numerators together and multiply the denominators together then reduce the result to its lowest terms.

Mixed fractions

Worked example

To multiply mixed fractions, first convert all the mixed fractions to improper fractions and then multiply the numerators together and the denominators together. Reduce the result to its lowest terms.

You can cancel out equivalent terms before you start the calculation. If you get into the habit of reducing fractions before multiplying, you will minimize errors when you multiply complex fractions and large numbers.

Now multiply the numerators and the denominators:
