Division by 10 and 100

In this activity, you 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

 

 

e.g. Work out:

37 ÷ 100

 

Answer:

Shift each digit two places to the right.

So 37 ÷ 100 =  0.37

 

 

e.g. Work out:

7 ÷ 100

 

Answer:

Shift each digit two places to the right.

Fill in the blank spaces with zeros.

So 7 ÷ 100 =  0.07

 

 

e.g. Work out:

30 ÷ 100

 

Answer:

Shift each digit two places to the right.

Leave off the last zero.

So 30 ÷ 100 =  0.30 = 0.3
