In this unit, pupils have explored the structure of fractions and their relationship with decimals and integers. This is built on in the future unit where pupils deepen their understanding of the arithmetic procedures involving fractions and integers.

In this unit, pupils will be asked to compare and order both fractions and decimals and will assess when conversion is required. Fluency in working with decimals and integers is an important skill which is developed in the prior unit.

Comparing and ordering fractions and decimals (positive and negative)

Using a calculator, calculate the simplified fraction of $$96 \over 90$$.

Using a calculator, work out the answer to $${16 \over 15} \times 315$$.

Sam's calculator gives an answer as a fraction. What is the name of the key that should be pressed first on the Casio fx-991CW in order to convert this fraction to a decimal?

Using a calculator, match the decimal to the equivalent fraction.

The format key on the Casio fx-991CW only allows you to change a decimal to an improper fraction.

Using your calculator, find the answer to $${4 \over 19} \times {26 \over 62}$$

Complete the statement. A factor is a {{ }} which exactly divides another {{ }}.

Select all the fractions that simplify to $$5 \over 8$$.

Which of the following factors of 48 and 180 is the best choice to efficiently simplify $$48\over180$$?

$$\frac{2^2 \times 3^2 \times 5}{2^2 \times 5^2 \times 7}$$

$$\frac{2^3 \times 3^2 \times 5}{2^2 \times 5 \times 7}$$

$$\frac{2^3 \times 3^2 \times 5^2}{2^2 \times 5^2 \times 7^2}$$

$$\frac{2^3 \times 3^2 \times 5}{2^2 \times 5^2 \times 7}$$

$$\frac{2^3 \times 3^3 \times 5}{2^2 \times 3 \times 5^2 \times 7}$$

Which of these fractions is equivalent to $$1080 \over 2100$$
