Let’s go through each part of the worksheet step by step.
---
Part 1: Divide these numbers by 10, 100 and 1,000
We remember:
→ Dividing by 10 → move decimal point 1 place to the left
→ Dividing by 100 → move decimal point 2 places to the left
→ Dividing by 1,000 → move decimal point 3 places to the left
Let’s fill in the table:
Row 1: 42
÷10 → 4.2
÷100 → 0.42
÷1000 → 0.042
Row 2: 156
÷10 → 15.6
÷100 → 1.56
÷1000 → 0.156
Row 3: 12.5
÷10 → 1.25
÷100 → 0.125
÷1000 → 0.0125
Row 4: 7 (same as 7.0)
÷10 → 0.7
÷100 → 0.07
÷1000 → 0.007
Row 5: 0.6
÷10 → 0.06
÷100 → 0.006
÷1000 → 0.0006
Row 6: 156.1
÷10 → 15.61
÷100 → 1.561
÷1000 → 0.1561
✔ Table filled correctly.

Part 2: Fill in the missing numbers
We’re looking for what number you divide by to get the answer.
Remember:
If A ÷ ? = B, then ? = A ÷ B
But actually, it’s easier to think:
What do I divide by to move the decimal point to get the result?
1.
468 ÷ ___ = 4.68
→ 468 → 4.68 → moved decimal 2 places left → divide by 100
✔ Answer: 100
2.
39.1 ÷ ___ = 0.0391
→ 39.1 → 0.0391 → moved decimal 3 places left → divide by 1000
✔ Answer: 1000
3.
88 ÷ ___ = 0.088
→ 88 → 0.088 → moved decimal 3 places left → divide by 1000
✔ Answer: 1000
4.
6.42 ÷ ___ = 0.0642
→ 6.42 → 0.0642 → moved decimal 2 places left → divide by 100
✔ Answer: 100
5.
410 ÷ ___ = 0.41
→ 410 → 0.41 → moved decimal 3 places left → divide by 1000
✔ Answer: 1000
6.
6300 ÷ ___ = 6.3
→ 6300 → 6.3 → moved decimal 3 places left → divide by 1000
✔ Answer: 1000

Part 3: Word Problems
7.
A pack of 1,000 pencils cost £40. How much would one pencil cost?
→ £40 ÷ 1000 = £0.04
✔ Answer: £0.04
8.
Mr Icy sold 100 ice creams for £85. How much was each ice cream?
→ £85 ÷ 100 = £0.85
✔ Answer: £0.85
9.
Tom bought 10 pizzas for £35.50. How much were they each?
→ £35.50 ÷ 10 = £3.55
✔ Answer: £3.55
10.
Zara has divided 356 by 10. Her answer is 3.56. Is she correct?
→ 356 ÷ 10 should be 35.6 (move decimal 1 place left)
→ She got 3.56 — that’s dividing by 100, not 10.
✔ So,
No, she is not correct.
Try to explain what Zara has done:
She moved the decimal point two places to the left instead of one. That means she divided by 100, not 10.
