Version 4 — Syllabus-first, not past-year derived
Section A (10 marks)
-
7 045 218 = Seven million forty-five thousand two hundred and eighteen. [1]
Teaching note: Read from millions: 7 (million), 045 (thousand), 218 (ones). -
Place value of 4 in 4 621 390 = Millions. [1]
Teaching note: Digit 4 is in the 7th position from right (millions place). -
3 847 215 → nearest hundred thousand = 3 800 000. [1]
Working: Hundred thousand digit is 8; next digit 4 (<5) so round down. -
2 500 000 + 340 000 + 8 000 + 60 = 2 848 060. [1]
Working: 2 500 000 + 340 000 = 2 840 000; +8 000 = 2 848 000; +60 = 2 848 060. -
9 000 000 − 8 456 321 = 543 679. [1]
Working: Direct subtraction. -
1 250 × 800 = 1 000 000. [1]
Working: 125 × 8 = 1 000; add four zeros (from 250 and 800) → 1 000 000. -
2 400 000 ÷ 12 000 = 200 boxes. [1]
Working: Cancel 000: 2 400 ÷ 12 = 200. -
5 300 000 = 5.3 million. [1]
Teaching note: 1 million = 1 000 000, so 5 300 000 ÷ 1 000 000 = 5.3. -
Greater: 6 210 455. [1]
Reason: Compare digit by digit; ten-thousands 1 > 0. -
4 800 000 ÷ 16 = 300 000. [1]
Working: 48 ÷ 16 = 3; add four zeros.
Section B (10 marks)
-
[2]
Difference = 3 245 000 − 2 987 500 = 257 500.
Marks: 1 for subtraction setup, 1 for correct answer. -
[2]
Total = 5 400 000 + 3 750 000 = 9 150 000.
Marks: 1 for addition, 1 for answer. -
[2]
Nearest million: 9 000 000 (since 8.749… rounds to 9).
Nearest thousand: 8 750 000 (hundreds digit 6 ≥5).
Marks: 1 each. -
[2]
Sold = 78 450 + 26 980 = 105 430. Left = 120 000 − 105 430 = 14 570.
Marks: 1 for total sold, 1 for remainder. -
[2]
3 204 × 250 = 3 204 × 25 × 10 = 80 100 × 10 = 801 000.
Marks: 1 for method, 1 for answer.
Section C (30 marks)
-
[4]
Spent = 1 280 000 + 640 000 = 1 920 000.
Saved = 2 450 000 − 1 920 000 = 530 000.
Per centre = 530 000 ÷ 10 = 53 000.
Marks: 1 spent, 1 saved, 1 division, 1 answer. -
[4]
B = 3 × 4 120 000 − 360 000 = 12 360 000 − 360 000 = 12 000 000.
Marks: 1 multiply, 1 subtract setup, 2 answer. -
[4]
Sent = 2 345 000 + 1 870 000 = 4 215 000.
Remain = 6 500 000 − 4 215 000 = 2 285 000.
Each = 2 285 000 ÷ 5 = 457 000.
Marks: 1 total sent, 1 remain, 1 divide, 1 answer. -
[4]
Lim yearly = 9 600 000 ÷ 12 = 800 000.
Friend yearly = 7 200 000 ÷ 12 = 600 000.
Diff = 200 000.
Marks: 1 each step. -
[4]
Cost per chair = 3 600 000 ÷ 24 000 = 150.
Profit per chair = 180 − 150 = 30.
Total profit = 30 × 24 000 = 720 000.
Marks: 1 unit cost, 1 profit/unit, 1 total profit, 1 answer.
