In this activity, we will be learning how to convert fractions involving 10ths, 100ths and 1,000ths.

Let's recap some helpful facts that will help us to convert fractions.

A thousandth is a tenth of a hundredth.

So 10 thousandths make 1 hundredth.

A hundredth is a tenth of a tenth.

So 10 hundredths make 1 tenth.

And 100 thousandths make 1 tenth too.

Let's try an example question.

**Example**

Find the missing numerators and denominators.

4/___ = 40/1000

3/10 = ___/1000

850/1000 = 85/___

**Answer**

4/**100** = 40/1000

3/10 = **300**/1000

850/1000 = 85/**100**

To multiply by 10, we move the digits **one column to the left.**

To multiply by 100, we move the digits** two columns to the left.**

To multiply by 1,000, we move the digits** three columns to the left.**

To divide by 10, 100 and 1000, we do the same steps as above, except the digits **move to the right** instead because the number gets smaller when we divide.

Now it's time to try some of these yourself!
