# Finding non-unit fractions of quantities

In this lesson, we will revisit what a non-unit fraction is. We will then use a 'bar modelling' strategy to help us calculate non-unit fractions of amounts. Finally, we will work backwards by applying this knowledge to use the value of the parts to help us calculate the total value of the quantity (whole).
