Ordering fractions by size - Method 3

Putting fractions in order smallest to largest can be achieved if you simply work out the fraction. Remember

 `1/2=0.5`

Example 1

Put the following fractions in order of the smallest to biggest fractions.

`8/3`   `5/4`   and   `12/5`

Ordering fractions by size method 3 example 1

Now we can clearly see that

`5/4`  is the smallest then  `12/5`  then  `8/3`

 

 

Example 2

Put the following fractions in order of the smallest to biggest fraction

`1/2`   `1/3`   `1/4`   `1/6`   `1/8`

Complete the sums:

Now you can clearly see that:

`1/8`  is the smallest followed by  `1/6`,  `1/4`  `1/3`  and  `1/2`

 

NOTE:

You should be familiar enough with fractions to realise that the biggest number divided into `1` would obviously be the smallest fraction.

 

Example 3

Which is greater `3/8`  or  `4/9`?

Complete the sums

So `3/8=0.375`  and  `4/9=0.4dot4`

Clearly `4/9`  is the larger fraction

 

 

Example 4

Put the following fractions in order of the smallest to biggest fraction

`2/6`   `1/2`   `7/16`   `3/4`   `5/8`

Complete the sums:

(Note: only go to a maximum of 2 decimal places)

Ordering fractions by size method 3 example 4

So `2/6=0.33`   `1/2=0.5`   `7/16=0.43`   `3/4=0.75`   `5/8=0.62`

We can clearly see that the order from the smallest is:

`2/6`   `7/16`   `1/2`   `5/8`   `3/4`
