## 🔢
Key Rule to Remember:
When you divide a decimal number by:
-
10 → move the decimal point
1 place to the left
-
100 → move the decimal point
2 places to the left
-
1,000 → move the decimal point
3 places to the left
If there aren’t enough digits, add zeros as placeholders.

✔ Part A: Find the Quotient
Let’s solve each one using the rule above.
---
1) 0.185 ÷ 10
→ Move decimal 1 place left:
0.0185
---
2) 25.05 ÷ 100
→ Move decimal 2 places left:
0.2505
---
3) 46.8 ÷ 1,000
→ Move decimal 3 places left:
0.0468
---
4) 5.81 ÷ 10
→ Move decimal 1 place left:
0.581
---
5) 6.7 ÷ 100
→ Move decimal 2 places left:
0.067
---
6) 3.6 ÷ 1,000
→ Move decimal 3 places left:
0.0036
---
7) 7.94 ÷ 10
→ Move decimal 1 place left:

Part B: Complete the Table
We’ll apply the same rules to each row.
| Number | ÷10 | ÷100 | ÷1,000 |
|--------|-------------|-------------|-------------|
| 20.8 | 2.08 | 0.208 | 0.0208 |
| 12.71 | 1.271 | 0.1271 | 0.01271 |
| 9.5 | 0.95 | 0.095 | 0.0095 |
| 0.72 | 0.072 | 0.0072 | 0.00072 |
| 87.6 | 8.76 | 0.876 | 0.0876 |
---
💡 How we got them:
-
20.8 ÷ 10 = 2.08 (1 left)
-
20.8 ÷ 100 = 0.208 (2 left)
-
20.8 ÷ 1,000 = 0.0208 (3 left)
Repeat for all rows using the same logic.

✔ Final Completed Table:
| Number | ÷10 | ÷100 | ÷1,000 |
|--------|--------|--------|--------|
| 20.8 | 2.08 | 0.208 | 0.0208 |
| 12.71 | 1.271 | 0.1271 | 0.01271|
| 9.5 | 0.95 | 0.095 | 0.0095 |
| 0.72 | 0.072 | 0.0072 | 0.00072|
| 87.6 | 8.76 | 0.876 | 0.0876 |

## 🎯 Summary
Dividing by powers of 10 is all about
moving the decimal point to the left based on how many zeros are in the divisor.
- 10 → 1 place
- 100 → 2 places
- 1,000 → 3 places
This is a super useful shortcut — no long division needed!
Let me know if you’d like to practice multiplying by 10, 100, 1,000 next — it’s the opposite direction! 😊
Parent Tip: Review the logic above to help your child master the concept of dividing decimals by 10 100 and 1000 worksheet.
