In this unit, pupils generalised and developed their fluency of multiplying with fractions. In the future unit, this understanding is extended to ratio and connections between ratios and fractions are explored.

In the prior unit, pupils explored the structure of fractions and their relationship with decimals and integers. In this unit, pupils deepen their understanding of the arithmetic procedures involving fractions and integers.

This unit revisits and secures fraction operations and extends pupil understanding to division of whole numbers by fractions and division of fractions by fractions.

Arithmetic procedures with fractions

Which of the following is $$3 {{2} \over {3}}$$ as an improper fraction?

(3 - 1) + $$\left(\frac13-\frac56\right)$$

(3 - 1) - $$\left(\frac13-\frac56\right)$$

Which of the following show a correct first step to calculate $$3 {{1} \over {3}}$$ - $$1 {{5} \over {6}}$$?

Which of the following can be simplified before calculating?

What is the missing digit in this calculation $$1 {{1} \over {3}}$$ + $$2 {{\square} \over {6}}$$ = $$4 {{1} \over {6}}$$?

Calculate $$3 {{1} \over {3}}$$ - $$1 {{5} \over {6}}$$, give your answer in its simplest form.
