Answer Key & Marking Scheme
Section A: Multiple Choice (10 marks)
1. What is the value of the digit 7 in the number 3,745,218?
Answer: D — 700,000
Working: The digit 7 is in the hundred thousands place. 3,745,218 → 7 × 100,000 = 700,000
Marks: 2
2. Round 4,567,892 to the nearest hundred thousand.
Answer: C — 4,600,000
Working: The hundred thousands digit is 5. The next digit (ten thousands) is 6, which is ≥ 5, so we round up. 4,567,892 → 4,600,000
Marks: 2
3. Which of the following is equal to 5 million?
Answer: B — 5,000,000
Working: 1 million = 1,000,000, so 5 million = 5 × 1,000,000 = 5,000,000.
Marks: 2
4. What is 6,000,000 ÷ 1,000?
Answer: B — 6,000
Working: Dividing by 1,000 removes 3 zeros. 6,000,000 ÷ 1,000 = 6,000
Marks: 2
5. The population of a town is 2,384,567. What is this number rounded to the nearest ten thousand?
Answer: A — 2,380,000
Working: The ten thousands digit is 8. The next digit (thousands) is 4, which is < 5, so we round down. 2,384,567 → 2,380,000
Marks: 2
Section B: Short Answer (20 marks)
6. Write in figures: Four million, two hundred and six thousand, and ninety-three.
Answer: 4,206,093
Working:
- Four million = 4,000,000
- Two hundred and six thousand = 206,000
- Ninety-three = 93
- Total: 4,000,000 + 206,000 + 93 = 4,206,093
Marks: 2
Common mistake: Writing 4,206,93 (missing a zero in the tens place). The number must have 7 digits.
7. Write in words: 7,083,415
Answer: Seven million, eighty-three thousand, four hundred and fifteen.
Working:
- 7,000,000 = Seven million
- 83,000 = Eighty-three thousand
- 415 = Four hundred and fifteen
Marks: 2
Common mistake: Omitting "and" before the last part, or writing "seven millions" (no plural needed).
8. Arrange from smallest to largest: 3,456,789 | 3,465,879 | 3,456,879 | 3,459,678
Answer: 3,456,789; 3,456,879; 3,459,678; 3,465,879
Working: Compare digit by digit from the left:
- All start with 3,45...
- 3,456,789 vs 3,456,879: same up to thousands; 789 < 879 → 3,456,789 is smaller
- 3,459,678: ten thousands digit is 9 (vs 6 in the others above) → larger
- 3,465,879: ten thousands digit is 6 → largest
Marks: 2
Marking note: Award 2 marks for correct order. Award 1 mark if only one pair is swapped.
9. 8,5_2,367 is between 8,540,000 and 8,560,000. What digit could go in the box?
Answer: 4 or 5 (accept either)
Working: The missing digit is in the ten thousands place.
- If the digit is 4: 8,542,367 ✓ (between 8,540,000 and 8,560,000)
- If the digit is 5: 8,552,367 ✓ (between 8,540,000 and 8,560,000)
Marks: 2
Accept: 4 or 5. Award 2 marks for either correct digit.
10. Complete the pattern: 1,250,000 | 1,500,000 | 1,750,000 | __________ | __________
Answer: 2,000,000 and 2,250,000
Working: The pattern increases by 250,000 each time.
- 1,750,000 + 250,000 = 2,000,000
- 2,000,000 + 250,000 = 2,250,000
Marks: 2
11. A factory produced 2,345,678 toys in January and 3,567,890 toys in February. How many in total?
Answer: 5,913,568
Working:
2,345,678
+ 3,567,890
-----------
5,913,568
Marks: 2
Common mistake: Misalignment of place values. Remind students to align digits by place value.
12. Find the product: 4,500 × 1,000 =
Answer: 4,500,000
Working: Multiplying by 1,000 adds 3 zeros. 4,500 × 1,000 = 4,500,000
Marks: 2
13. Evaluate: 6 + 4 × 3 − 8 ÷ 2
Answer: 14
Working (BODMAS):
- Multiplication: 4 × 3 = 12
- Division: 8 ÷ 2 = 4
- Addition and subtraction from left to right: 6 + 12 − 4 = 14
Marks: 2
Common mistake: Students who work strictly left to right without applying BODMAS will get 6 + 4 = 10, × 3 = 30, − 8 = 22, ÷ 2 = 11 (incorrect).
14. A number has 3 millions, 4 hundred thousands, 0 ten thousands, 7 thousands, 2 hundreds, 5 tens, and 8 ones.
Answer: 3,407,258
Working:
| Millions | Hundred Thousands | Ten Thousands | Thousands | Hundreds | Tens | Ones |
|---|---|---|---|---|---|---|
| 3 | 4 | 0 | 7 | 2 | 5 | 8 |
Marks: 2
Common mistake: Forgetting the 0 in the ten thousands place, resulting in 3,472,58 or similar.
15. Round 8,476,235 to the nearest million.
Answer: 8,000,000
Working: The millions digit is 8. The next digit (hundred thousands) is 4, which is < 5, so we round down. 8,476,235 → 8,000,000
Marks: 2
Section C: Structured / Problem Solving (20 marks)
16. (3 marks)
| Library | Number of Books |
|---|---|
| Red | 1,234,567 |
| Blue | 1,324,567 |
| Green | 1,234,657 |
| Yellow | 1,243,567 |
(a) Which library has the most books? (1 mark)
Answer: Blue
Working: Compare the numbers. Blue (1,324,567) has the largest hundred thousands digit (3 vs 2 in all others).
(b) Which library has the fewest books? (1 mark)
Answer: Red
Working: Red (1,234,567) — comparing with Green (1,234,657): same up to hundreds, but 567 < 657, so Red is smallest.
(c) How many more books does the library with the most have than the library with the fewest? (1 mark)
Answer: 90,000
Working: 1,324,567 − 1,234,567 = 90,000
Marks: 1 + 1 + 1 = 3

Marking note: Award 1 mark for correct working even if the final answer has an arithmetic error.
18. (4 marks)
Singapore population: 5,917,600 Malaysia population: 34,308,000
(a) Round each to the nearest million: (2 marks)
Singapore: 6,000,000
- Hundred thousands digit is 9 (≥ 5), so round up: 5,917,600 → 6,000,000
Malaysia: 34,000,000
- Hundred thousands digit is 3 (< 5), so round down: 34,308,000 → 34,000,000
(b) Estimate the total population: (2 marks)
Answer: 40,000,000
Working: 6,000,000 + 34,000,000 = 40,000,000
Marks: 2 + 2 = 4
19. (4 marks)
A warehouse had 4,500,000 packets of rice packed equally into 1,000 boxes.
(a) Packets per box: (2 marks)
Answer: 4,500
Working: 4,500,000 ÷ 1,000 = 4,500
(b) Each box divided equally among 10 shops. Packets per shop: (2 marks)
Answer: 450
Working: 4,500 ÷ 10 = 450
Alternative (one-step): 4,500,000 ÷ 1,000 ÷ 10 = 4,500,000 ÷ 10,000 = 450
Marks: 2 + 2 = 4
20. (5 marks)
Digits: 3 | 8 | ? | 5 | 2 | 1 | 7
The number is between 3,850,000 and 3,860,000.
(a) What digit could go in the box? (1 mark)
Answer: 5 (accept 5 only, since the number must be ≥ 3,850,000 and < 3,860,000)
Working: The number is 3,8?5,217. For it to be between 3,850,000 and 3,860,000, the ten thousands digit must be 5.
- If ? = 5: 3,855,217 ✓ (between 3,850,000 and 3,860,000)
- If ? = 4: 3,845,217 ✗ (less than 3,850,000)
- If ? = 6: 3,865,217 ✗ (greater than 3,860,000)
(b) Write the full number in words. (2 marks)
Answer: Three million, eight hundred and fifty-five thousand, two hundred and seventeen.
(c) Round to the nearest hundred thousand. (2 marks)
Answer: 3,900,000
Working: The hundred thousands digit is 8. The next digit (ten thousands) is 5, which is ≥ 5, so we round up. 3,855,217 → 3,900,000
Marks: 1 + 2 + 2 = 5
