Multiplying decimals by 10

When we multiply decimal numbers by 10 we move the decimal point one space to the right.

Example: 

4.5678 × 10 = 45.678

 

Multiplying decimals by 100

When we multiply decimal numbers by 100 we move the decimal point two spaces to the right.

Example:

4.5678 × 100 = 456.78

 

Multiplying decimals by 1000

When we multiply decimal numbers by 1000 we move the decimal point three spaces to the right.

Example:

4.5678 × 1000 = 4567.8

 

Do you see how the number of spaces we move the decimal point is the same as the amount of zeros? 10 has 1 zero, 100 has 2 zeros and 1000 has 3 zeros.
