Dividing by powers of ten
Divide whole numbers and decimals by 10, 100 or 1000.
- Divide by 10: move every digit one place right in a place-value chart.
- Divide by 100: move two places; by 1000: move three.
- Include a zero before a decimal point when the value is less than one.
Example 1
Calculate.
Digits move 2 places right, to smaller values.
The decimal point stays fixed in a place-value chart.
Example 2
Calculate.
Digits move 3 places right, to smaller values.
The decimal point stays fixed in a place-value chart.
Remember
Include a zero before a decimal point when the value is less than one.
