SA2 (Version 5 of 5) — Answer Key

---

Section A: Multiple Choice Questions (10 marks)

1. What is the value of the digit 7 in the number 3,708,452?

Answer: (D) 700,000 [1]

Working: The digit 7 is in the hundred thousands place. 3,708,452 → 7 × 100,000 = 700,000

---

2. Round 4,567,891 to the nearest hundred thousand.

Answer: (C) 4,600,000 [1]

Working: The hundred thousands digit is 5. The ten thousands digit is 6 (≥ 5), so we round up. 4,567,891 → 4,600,000

---

3. Which of the following is the smallest number?

Answer: (C) 2,009,999 [1]

Working: All numbers start with 2 million. Compare the next digits:

• (A) 2,099,999 → hundred thousands digit = 9
• (B) 2,100,001 → hundred thousands digit = 1 (but ten thousands = 0, thousands = 0)
• (C) 2,009,999 → hundred thousands digit = 0, ten thousands = 0, thousands = 9
• (D) 2,010,000 → hundred thousands digit = 0, ten thousands = 1

Comparing (C) and (D): 2,009,999 vs 2,010,000 → 2,009,999 is smaller.

---

4. 8,000,000 ÷ 1,000 = ?

Answer: (B) 8,000 [1]

Working: 8,000,000 ÷ 1,000 = 8,000 (remove 3 zeros)

---

5. Write "nine million, three hundred five thousand and sixty-two" in numerals.

Answer: (B) 9,305,062 [1]

Working: Nine million = 9,000,000; three hundred five thousand = 305,000; sixty-two = 62. 9,000,000 + 305,000 + 62 = 9,305,062

---

6. What is 10,000 more than 5,498,237?

Answer: (A) 5,508,237 [1]

Working: 5,498,237 + 10,000 = 5,508,237

---

7. The product of 2,500 × 400 is:

Answer: (C) 1,000,000 [1]

Working: 2,500 × 400 = 25 × 100 × 4 × 100 = 25 × 4 × 10,000 = 100 × 10,000 = 1,000,000

---

8. Which number is 100,000 less than 7,000,000?

Answer: (A) 6,900,000 [1]

Working: 7,000,000 − 100,000 = 6,900,000

---

9. Arrange from greatest to least: 3,456,789 | 3,465,789 | 3,456,879

Answer: (B) 3,465,789, 3,456,879, 3,456,789 [1]

Working: All start with 3,45_. Compare the thousands digit:

• 3,465,789 → thousands digit = 6 (greatest)
• 3,456,879 → thousands digit = 5, hundreds = 8
• 3,456,789 → thousands digit = 5, hundreds = 7

Between the last two: 3,456,879 > 3,456,789 (since 879 > 789).

---

10. A factory produced 1,250,000 toys in January and 2,750,000 toys in February. How many in total (in millions)?

Answer: (C) 4 million [1]

Answer: 4,000,000, 4,250,000 [2]

Working: The pattern increases by 250,000 each time. 3,750,000 + 250,000 = 4,000,000 4,000,000 + 250,000 = 4,250,000

Marking: 1 mark for each correct term.

---

(b) 9,999,990, 9,999,980, 9,999,970, __________, __________

Answer: 9,999,960, 9,999,950 [2]

Working: The pattern decreases by 10 each time. 9,999,970 − 10 = 9,999,960 9,999,960 − 10 = 9,999,950

Marking: 1 mark for each correct term.

---

14. Find the value.

(a) 6,000,000 ÷ 10,000

Answer: 600 [1]

Working: 6,000,000 ÷ 10,000 = 6,000,000 ÷ 10⁴ = 600

---

(b) 45,000 × 100

Answer: 4,500,000 [1]

Working: 45,000 × 100 = 45,000 × 10² = 4,500,000

---

(c) 7,200,000 ÷ 1,000 × 10

Answer: 72,000 [1]

Working: 7,200,000 ÷ 1,000 = 7,200; then 7,200 × 10 = 72,000

Common mistake: Students may multiply before dividing. Correct order: left to right for same-level operations.

---

15. Population problem.

(a) New population

Answer: 4,612,995 [2]

Working: Starting population: 4,567,890 People moved in: + 234,567 People moved out: − 189,432

4,567,890 + 234,567 = 4,802,457 4,802,457 − 189,432 = 4,613,025

Correction: 4,567,890 + 234,567 = 4,802,457 4,802,457 − 189,432 = 4,613,025

Answer: 4,613,025 [2]

Marking: 1 mark for correct addition step, 1 mark for correct final answer.

---

(b) Round to nearest million.

Answer: 5,000,000 (or 5 million) [1]

Working: 4,613,025 → The hundred thousands digit is 6 (≥ 5), so round up to 5,000,000.

---

Section C: Structured / Problem-Sum Questions (20 marks)

16. Donation collection.

(a) Total amount collected

Answer: $477,635 [2]

Working: $125,430 +$98,765 + $142,890 +$110,550

Marking: 1 mark for correct method/working, 1 mark for correct answer.

---

(b) Round each to nearest ten thousand and find estimated total.

Answer: $480,000 [2]

Working:

• 5A: $125,430 → nearest ten thousand =$130,000 (thousands digit 5, round up)
• 5B: $98,765 → nearest ten thousand =$100,000 (thousands digit 8, round up)
• 5C: $142,890 → nearest ten thousand =$140,000 (thousands digit 2, round down)
• 5D: $110,550 → nearest ten thousand =$110,000 (thousands digit 0, round down)

Estimated total: $130,000 +$100,000 + $140,000 +$110,000 = $480,000

Marking: 1 mark for correct rounding of all four values, 1 mark for correct estimated total.

Answer: History Museum (1,987,654), Art Museum (2,345,678), Nature Museum (2,765,432), Science Museum (3,102,456) [2]

Working: Compare digit by digit from the left. All are 7-digit numbers starting with different millions digits: 1 < 2 < 2 < 3. For the two starting with 2: 2,345,678 < 2,765,432 (since 3 < 7 in the hundred thousands place).

Marking: 1 mark for correct order, 1 mark for all four in correct positions.

---

(c) Difference between greatest and least

Answer: 1,114,802 [2]

Working: 3,102,456 − 1,987,654 = 1,114,802

• X: 3,546,789 → hundred thousands digit = 5 (largest)
• Y: 3,456,879
• Z: 3,465,789

Country X has the largest hundred thousands digit (5), so it is the largest.

---

(b) Where does Country V (3,500,000 sq km) fit?

Answer: Country V fits between Country Z and Country X. [3]

Working: Arrange all five from smallest to largest:

• W: 3,456,789
