Let's solve the problems step by step using the
"Step to success" rule:
>
✔ Rule: When dividing decimals by 10, 100, or 1000:
> - Count the number of zeros in the divisor.
> - Move the decimal point to the
left by that many places.

🔹 Problem 3: Division by 1000 (3 zeros → move decimal 3 places left)
A) 9 ÷ 1000
- 9 is the same as 9.0
- Move decimal 3 places left → 0.009
✔ Answer: 0.009
---
B) 9009 ÷ 1000
- 9009.0 → move decimal 3 places left → 9.009
✔ Answer: 9.009
---
C) 890 ÷ 1000
- 890.0 → move decimal 3 places left → 0.890
- We can write it as
0.89 (since trailing zero after decimal doesn't change value, but 0.890 is also correct).
✔ Answer: 0.890 or 0.89
