In this activity, you will need to find a simple fraction of a number of objects.

 

Example

How many apples will be there in one third or 1/3 of the number of apples below?

 

   

   

   

 

Answer

To find one third or 1/3 of a number of objects we share or divide them into 3 equal groups.

 

   

 

 

   

 

 

   

 

There are 4 apples in each group so one third or 1/3 of 12 is 4

This is the same as working out 12 ÷ 3 = 4

 

To find one half or 1/2 of a number, we divide by 2.

Can you find 1/2 of these bananas?

 

 

Share the bananas into 2 equal groups. 

 

 

 

 

There are 7 bananas in each group, so 14 ÷ 2 = 7

 

 

To find one quarter or 1/4 of a number, we divide by 4.

Can you find 1/4 of these cakes?

 

 

There are 20 cakes. If we share them into 4 equal groups, there will be 5 in each group: 20 ÷  4 = 5

So 1/4 of 20 is 5.
