When it comes to multiplying fractions, it's actually very similar to multiplying whole numbers. We just work with smaller parts, but the process is the same. We can work out multiplication using different methods, including:

pictures and area models (we use this to add and subtract fractions as well)

a number line (you can see how we add fractions with a number line)

repeated addition

times tables

Multiplying unit fractions

A unit fraction is a fraction with a numerator (top number) of $1$1. In this video, all the multiplication we do involves multiplying unit fractions by whole numbers.
