Ordering fractions
- The denominator is the number on the bottom of a fraction.
- It is easy to order fractions when the denominators are the same.
- All the fractions above have a denominator of 8.

Ordering fractions 2
- As the denominators are the same, you look to the numerators to order from smallest to largest.
Comparing Unit Fractions
You can easily order unit fractions by comparing their denominators.
Comparing unit fractions
- Which is bigger, 1/2 or 1/3?
- We can work out the fractions of numbers to help us.
- I know 1/2 of 12 = 6 (because 12 ÷ 2 = 6).
- I know 1/3 of 12 = 4 (because 12 ÷ 3 = 4).
- So 1/2 is bigger than 1/3.
Ordering unit fractions
- Unit fractions can be ordered by looking at their denominators.
- The smaller the denominator, the bigger the fraction.
- So to order the fractions shown from smallest to biggest, we have to order the denominators from biggest to smallest.
