Divide by a Number with One Decimal Place

In this activity, we will learn how to divide a number by another number with one decimal place.

 

Remember that 240 ÷ 10 is the same as 24 ÷ 1 = 24

So 24 ÷ 1.2 is the same as 240 ÷ 12 = 20

 

Method 

To divide a number by a number with one decimal place:

First of all, we need to multiply both numbers by 10.  

 

You need to do the same thing to both numbers or it won't be correct!

 

Your answer will be the same as dividing the original numbers. Prove it to yourself by checking with your calculator!

 

 

Example

36.25 ÷ 0.5

 

Answer

We multiply both numbers by 10 and work out 362.5 ÷ 5

  

Answer is 72.5

 

Does that make sense? It's simple really once you get a bit of practice in!
