TuitionGoWhere Practice Paper - Mathematics Primary 5 (Answer Key)

Subject: Mathematics
Level: Primary 5
Paper: Practice Paper 2 (Version 2 of 5)
Total Marks: 80

SECTION A: Multiple-Choice Questions (20 marks)

1. Answer: (2) 7 [2]

Explanation: In 4 728 593, the digits from left to right are: 4 (millions), 7 (hundred thousands), 2 (ten thousands), 8 (thousands), 5 (hundreds), 9 (tens), 3 (ones). The digit in the hundred thousands place is 7.

2. Answer: (2) 6 850 000 [2]

Explanation: To round to the nearest ten thousand, look at the thousands digit (9 in 6 849 327). Since 9 ≥ 5, round up the ten thousands digit from 4 to 5. All digits to the right become 0. Result: 6 850 000.

3. Answer: (1) 5 346 295 [2]

Explanation: Add by place value: 5 000 000 + 300 000 = 5 300 000; + 40 000 = 5 340 000; + 6 000 = 5 346 000; + 200 = 5 346 200; + 90 = 5 346 290; + 5 = 5 346 295.

4. Answer: (2) 4 767 890 [2]

Explanation: 4 567 890 + 200 000 = 4 767 890. Add 200 000 to the hundred thousands place: 5 + 2 = 7 hundred thousands.

5. Answer: (2) 720 [2]

Explanation: Using order of operations (BODMAS): Brackets first: 48 + 12 = 60. Then multiplication and division from left to right: 72 × 60 = 4 320; 4 320 ÷ 6 = 720.

6. Answer: (2) 11 734 [2]

Explanation: February production = January production + 3 278 = 8 456 + 3 278 = 11 734.

7. Answer: (1) 6 000 [2]

Explanation: 3 456 789 = 3 000 000 + 400 000 + 50 000 + 6 000 + 700 + 80 + 9. The missing value is 6 000 (thousands place).

8. Answer: (1) 108 200 [2]

Explanation: 4 328 × 25 = 4 328 × (100 ÷ 4) = 432 800 ÷ 4 = 108 200. Alternatively: 4 328 × 20 = 86 560; 4 328 × 5 = 21 640; 86 560 + 21 640 = 108 200.

9. Answer: (1) 654 [2]

Explanation: 7 848 ÷ 12 = 654. Check: 654 × 12 = 654 × 10 + 654 × 2 = 6 540 + 1 308 = 7 848.

10. Answer: (2) 5 600 499 [2]

Explanation: When rounding to the nearest thousand, numbers from 5 599 500 to 5 600 499 round to 5 600 000. Option (2) 5 600 499 falls in this range. Option (1) rounds to 5 599 000; options (3) and (4) round to 5 601 000.

SECTION B: Short-Answer Questions (30 marks)

11. Eight million forty-five thousand six hundred and two [2]

18. 2 350 000 [2]

Explanation: The pattern decreases by 50 000 each time: 2 500 000 → 2 450 000 → 2 400 000 → 2 350 000 → 2 300 000.

19. 1 260 km [2]

Working: 45 km/litre × 28 litres = 1 260 km. (45 × 28 = 45 × 20 + 45 × 8 = 900 + 360 = 1 260)

20. 480 [2]

Working: Brackets first: 125 + 75 = 200. Then: 48 × 200 ÷ 20 = 48 × 10 = 480. (Divide 200 by 20 first to simplify)

21. 240 [3]

Working: 8 640 ÷ 36 = 240 pens per box.

x − y = 1 200
Add both equations: 2x = 9 700 → x = 4 850.
Alternative: Larger number = (Sum + Difference) ÷ 2 = (8 500 + 1 200) ÷ 2 = 9 700 ÷ 2 = 4 850.
Mark breakdown: 1 mark for method (formula or simultaneous equations), 1 mark for correct calculation, 1 mark for correct answer.
