Divide by 3,4 & 8

In this activity, we will be learning about how to use the 3, 4, and 8 times table facts to solve division problems.

 

Multiplication and division are inverse operations. 

This means that if you know your 3 times table, you can also divide some numbers by 3 very quickly. 

Let's see how!

 

We know that 5 × 3 = 15. 

This means that in 15, there are 3 groups of 5 or 5 groups of 3. 

 

When we know one times table fact, we can write a family of facts by rearranging the numbers:

5 × 3 = 15

3 × 5 = 15

15 ÷ 3 = 5

15 ÷ 5 = 3

 

This works for all times table facts. 

So, if we know 2 × 8 = 16, we also know 16 ÷ 8 = 2!

 

Let's try an example using the 4 times table. 


Example

What is 24 ÷ 4?

 

Answer

We know that 24 is in the 4 times table. 

4 × 6 = 24

So, we can also say that 24 ÷ 4 = 6

 

Now that you've seen how to use this skill, you are ready to move on to some questions by yourself.
