Multiplying fractions

Lesson

We've seen how using the rule for multiplying fractions helps to simplify the process. Now we can try this out on fractions with *any* denominator, and look at how to work with mixed fractions and improper fractions in more detail.

Remember!

A whole number can be expressed as a fraction, we just use $1$1 as its denominator. Multiplying fractions can be done in different ways, so you may like to change mixed fractions to improper fractions before multiplying, but you don't have to.
