In this activity, we will **divide** whole numbers by **10** and **100**.

When we divide by 10, we shift each digit one place to the right.

So 64 ÷ 10 = 6.4

When we divide by 100, we shift each digit two places to the right.

So 64 ÷ 100 = 0.64

Notice how we needed to put a place holder in the ones column to show there are 0 ones.

__Example__

Work out:

37 ÷ 100

**Answer**

Shift each digit two places to the right (and add a 0 as a place holder to show there are 0 ones)

So 37 ÷ 100 = **0.37**

**Example**

Work out:

7 ÷ 100

**Answer**

Shift each digit two places to the right.

We need to use place holders in the ones and tenths columns to show there are 0 ones and 0 tenths.

So 7 ÷ 100 = **0.07**

__Example__

Work out:

30 ÷ 100

**Answer**

Shift each digit two places to the right.

Leave off the last zero - we don't need to show that there are no hundredths.

So 30 ÷ 100 = 0.30 = **0.3**
