Multiplying by powers of ten
Multiply whole numbers and decimals by 10, 100 or 1000.
- Multiply by 10: move every digit one place left in a place-value chart.
- Multiply by 100: move two places; by 1000: move three.
- Use zeros as placeholders where needed.
Example 1
Calculate.
Digits move 2 places left, to larger values.
The decimal point stays fixed in a place-value chart.
Example 2
Calculate.
Digits move 3 places left, to larger values.
