Ordering fractions
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
Ordering fractions 2
- As the denominators are the same, you look to the numerators to order from smallest to largest.
Compare and Order Fractions with Different Denominators
Compare and Order Fractions with Different Denominators
When the denominators (the numbers on the bottom of fractions) are different, you need to change one or more of the fractions so that they all have the same denominator.

Changing fractions
Changing fractions
- In order to work out which is larger, you need to make sure both fractions have the same denominator.
- As 8 is a multiple of 4, you can easily change our into eighths.

What do you need to multiply by?
What do you need to multiply by?
- First, you look at the denominator.
- You need to multiply the denominator of (4) by 2 to make 8.


Same to the top and bottom
Same to the top and bottom
- Remember:
- Whatever you do to the denominator you must do to the numerator.

Multiply the top by the same
Multiply the top by the same
- If you multiply our numerator of (3) by 2, our numerator will become 6.
- So is equivalent to (the same value as) .

Using < and >
Using < and >
- You can show which fraction is bigger using symbols.
- '<' means 'is smaller than'.
- 3 < 4 (3 'is smaller than' 4).
- '>' means 'is greater than'.
- 4 > 3 (4 'is greater than' 3).
