Total Marks: 40

Section A (10 marks)

Q1. [1 mark]
Answer: Four million two hundred fifty thousand three hundred eighteen.
Teaching note: Read the number in groups of three digits from the right: 4 | 250 | 318. "4" is millions, "250" is thousands, "318" is ones.

Q2. [1 mark]
Answer: Millions.
Teaching note: In 7 432 105, the digits from right are ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions. The 7 is in the millions place.

Q3. [1 mark]
Answer: 9 600 412.
Teaching note: Nine million = 9 000 000; six hundred thousand = 600 000; four hundred = 400; twelve = 12. Sum = 9 600 412.

Q4. [1 mark]
Answer: 4 000 000.
Teaching note: 3 847 291 is closer to 4 000 000 than to 3 000 000 because the hundred-thousands digit is 8 (≥5), so we round up.

Q5. [1 mark]
Answer: 5 000 000 (five million).
Teaching note: The digit 5 is in the millions place, so its value is 5 × 1 000 000 = 5 000 000.

Q6. [1 mark]
Answer: 2 135 000, 2 315 000, 2 351 000, 2 531 000.
Teaching note: Compare digit by digit from the left. All start with 2 million; then compare hundred-thousands: 1 < 3 < 3 (then ten-thousands 1<5) < 5.

Q7. [1 mark]
Answer: 8 140 222.
Teaching note: Compare millions (all 8), then hundred-thousands: 0 < 1 < 4. So 8 140 222 is greatest.

Q8. [1 mark]
Answer: 6 432 010.
Teaching note: Add the values: 6 000 000 + 400 000 = 6 400 000; +30 000 = 6 430 000; +2 000 = 6 432 000; +10 = 6 432 010.

Q9. [1 mark]
Answer: 9 700 000.
Teaching note: Hundred-thousands digit is 7 (≥5), so round 9 749 555 up to 9 700 000.

Q10. [1 mark]
Answer: 345.
Teaching note: 3 450 000 ÷ 10 000 = 345. There are 345 ten-thousands.

(a) 7 654 000
(b) 7 650 000

Marking: 1 mark each.

Q15. [2 marks]
Answer: 8 000 000 + 70 000 + 3 000 + 500.

Marking: 1 mark for correct decomposition, 1 mark for complete form.

Section C (20 marks)

Q16. [4 marks]
Answer: 2 135 000 kg left.
Working:
Total sent = 2 135 000 + 1 980 000 = 4 115 000 kg.
Left = 6 250 000 − 4 115 000 = 2 135 000 kg.
Marking: 1 mark total sent, 1 mark subtraction, 2 marks correct final answer with unit.

Q17. [4 marks]
Answer: 3 355 557 bricks not used.
Working:
Used = 3 456 789 + 2 987 654 = 6 444 443.

Answer: Total = 4 605 500; rounded = 4 600 000.
Working:
1 250 000 + 2 375 000 = 3 625 000.
3 625 000 + 980 500 = 4 605 500.
Nearest hundred thousand: ten-thousands digit is 0 (<5) → 4 600 000.
Marking: 2 marks total, 1 mark rounding, 1 mark both answers.

Q19. [4 marks]
Answer: 2 160 stickers per packet.
Working:
8 640 000 ÷ 4 000 = 8 640 ÷ 4 = 2 160.
Marking: 2 marks for division setup, 2 marks correct answer.

Q20. [4 marks]
Answer: Increase = 20 000; rounded = 20 000 (nearest ten-thousand).
Working:
5 920 000 − 5 900 000 = 20 000.
Nearest ten-thousand: 20 000 is already a multiple of 10 000.
Marking: 2 marks difference, 2 marks rounding and final.
