Let’s solve each problem step by step. When you divide a decimal by a power of 10 (like 10, 100, 1,000, or 10,000), you move the decimal point to the
left — one place for every zero in the divisor.
For example:
- Dividing by 10 → move decimal 1 place left
- Dividing by 100 → move decimal 2 places left
- Dividing by 1,000 → move decimal 3 places left
- Dividing by 10,000 → move decimal 4 places left
If there aren’t enough digits, add zeros on the left as needed.
