Here we will learn about** ordering fractions**.

There are also ordering fractions* *worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.

**Ordering fractions** is where we rearrange a set of fractions so that the smallest is at the start, followed by the next smallest and so on. This is called **ascending **order.

To do this we rewrite the fractions so that they have the same denominators which we can then compare.

We can order any type of fraction including proper fractions, improper fractions and mixed numbers.

E.g.

Write these fractions in ascending order:

Write the following fractions in order of size:

\[\frac{3}{4} \quad \quad 0.55 \quad \quad \frac{1}{2} \quad \quad 0.6 \]

**Write all the fractions so that they have a common denominator**

When there is a mixture of decimals and fractions it is sometimes easier to write them all as decimals. Some fractions and their decimal equivalents may be well known, otherwise we may need to work out a division.

\[\frac{3}{4}=3\div4=0.75\]

\[\frac{1}{2}=1\div2=0.5\]

**Find the smallest fraction by comparing the numerators and order the fractions**

Here are the numbers as decimals. To help with comparing it is a good idea to put in a zero in the hundredths column for

\[0.75 \quad \quad 0.55 \quad \quad 0.50 \quad \quad 0.60 \]

Writing them in size order would give

\[0.50 \quad \quad 0.55 \quad \quad 0.60 \quad \quad 0.75 \]

**Rewrite the numbers as they appear in the question in size order**

\[0.50 \quad \quad 0.55 \quad \quad 0.60 \quad \quad 0.75 \]

\[\frac{1}{2} \quad \quad \;\;\;0.55 \quad \quad \; 0.6 \quad \quad \;\; \frac{3}{4} \]

Write the following numbers in order of size:

\[0.67 \quad \quad \frac{2}{3} \quad \quad 0.603 \quad \quad \frac{5}{8} \]

**Write all the fractions so that they have a common denominator**

When there is a mixture of decimals and fractions it is sometimes easier to write them all as decimal fractions (decimals). Some fractions and their decimal equivalents may be well known, otherwise we may need to work out a division.

\[\frac{2}{3}=2\div3=0.666…\]

\[\frac{5}{8}=5\div8=0.625\]

**Find the smallest fraction by comparing the numerators and order the fractions**

Here are the numbers as decimals. To help with comparing it is a good idea to put in a zero in the thousandths column for

\[0.670 \quad \quad 0.666… \quad \quad 0.603 \quad \quad 0.625 \]

Writing them in size order would give

\[0.603 \quad \quad 0.625 \quad \quad \quad 0.666… \quad \quad 0.670 \]

**Rewrite the numbers as they appear in the question in size order**

\[0.603 \quad \quad 0.625 \quad \quad 0.666… \quad \quad 0.670 \]

\[0.603 \quad \quad \;\;\;\frac{5}{8} \quad \quad \;\; \; \; \;\frac{2}{3} \quad \quad \; \; \;\;\; 0.67 \]

**Changing the numbers into the same type of fractions**

It is much easier to change the fractions so that they have a common denominator and then compare the numerators.

**Use decimals if the common denominator is too tricky to find**

Sometimes finding a common denominator can be very difficult so it can be easier to convert the fractions to decimals and compare them instead.

**Smallest to largest or largest to smallest**?

Usually “in size order” means from smallest to largest. But the question might want you to put the numbers in descending order from largest to smallest.

E.g.

Write these numbers in order of size from largest to smallest:

\[\frac{4}{7} \quad \quad\frac{11}{14}\quad \quad \frac{1}{2}\]

Convert the fractions so they have the same denominator:

\[\frac{8}{14} \quad \quad \frac{11}{14} \quad \quad \frac{7}{14}\]

Write the fractions in order of size from largest to smallest:

\[\frac{11}{14} \quad \quad\frac{8}{14} \quad \quad \frac{7}{14}\]

The final answer is:

\[\frac{11}{14} \quad \quad \frac{4}{7} \quad \quad \frac{1}{2} \]
