Total Marks: 50
Section A: Multiple Choice Questions (10 × 1 mark = 10 marks)
| Qn | Answer | Explanation |
|---|---|---|
| 1 | (1) 15,372 | 427 × 36 = 427 × 30 + 427 × 6 = 12,810 + 2,562 = 15,372 |
| 2 | (2) 70 | 5,600 ÷ 80 = 560 ÷ 8 = 70 (cancel one zero from both numbers) |
| 3 | (4) All of the above | 345 × 20 = 345 × 2 × 10 = 345 × 10 × 2 = 345 × 4 × 5 = 6,900 |
| 4 | (1) 702 | 8,424 ÷ 12 = 702 (12 × 700 = 8,400; 12 × 2 = 24; 8,400 + 24 = 8,424) |
| 5 | (1) 2,880 | 24 × 15 = 360 biscuits per box; 360 × 8 = 2,880 |
| 6 | (2) 20 | 6,000 ÷ 300 = 20 |
| 7 | (3) 90 | 4,320 ÷ 48 = 90 (48 × 90 = 4,320) |
| 8 | (1) 5 | 27 × 35 = 27 × (30 + 5) = 27 × 30 + 27 × 5 (distributive property) |
| 9 | (1) 35,000 | 1,250 × 7 = 8,750 per week; 8,750 × 4 = 35,000 |
| 10 | (4) 2,940 ÷ 40 | 2,940 ÷ 40 = 73 remainder 20 (40 × 73 = 2,920; 2,940 - 2,920 = 20). Others divide exactly. |
Section B: Short Answer Questions (10 × 2 marks = 20 marks)
| Qn | Answer | Working / Explanation |
|---|---|---|
| 11 | 93,312 | 3,456 × 27 = 3,456 × 20 + 3,456 × 7 = 69,120 + 24,192 = 93,312 |
| 12 | 528 | 7,392 ÷ 14 = 528 (14 × 500 = 7,000; 14 × 28 = 392; 7,000 + 392 = 7,392) |
| 13 | 6,000 | 48 × 125 = 48 × (100 + 25) = 4,800 + 1,200 = 6,000. Alternatively: 48 × 125 = (48 ÷ 8) × (125 × 8) = 6 × 1,000 = 6,000 |
| 14 | 5,850 g | 325 × 18 = 325 × 10 + 325 × 8 = 3,250 + 2,600 = 5,850 g |
| 15 | 80 | 2,560 ÷ 32 = 80 (32 × 80 = 2,560) |
| 16 | 100 | 56 × 300 = 56 × 3 × 100 (since 300 = 3 × 100) |
| 17 | 1,223 | Total chairs = 45 × 28 = 1,260; Not broken = 1,260 - 37 = 1,223 |
| 18 | 72 | 8,640 ÷ 120 = 72 (120 × 72 = 8,640) |
| 19 | 60 | Total oranges = 15 × 36 = 540; Bags = 540 ÷ 9 = 60 |
| 20 | 11,250 | 450 × 25 = 450 × 20 + 450 × 5 = 9,000 + 2,250 = 11,250 |
Common Mistakes to Watch For:
- Section A Q10: Students may not check all options for remainders. Teach them to test each division.
- Section B Q13: Encourage using the "halving and doubling" trick: 48 × 125 = (48 ÷ 8) × (125 × 8) = 6 × 1,000 = 6,000.
- Section B Q17: Remember to subtract the broken chairs from the total.
- Units: Always include units (g, ml, litres, $) in final answers for word problems.
- Remainder problems: Emphasise "maximum number" means whole number quotient, not decimal.
