Answers
Primary 4 Mathematics Quiz - Multiplication Division (Answer Key)
Total Marks: 50
Section A: Multiple-Choice Questions (Questions 1–5, 5 × 1 mark = 5 marks)
1. C
Working: 324 × 7 = (300 × 7) + (20 × 7) + (4 × 7) = 2,100 + 140 + 28 = 2,268
Key concept: Multiply each digit by place value and add.
Explanation: Break 324 into 300, 20, and 4. Multiply each part by 7, then add the results.
Marking: 1 mark for correct answer.
2. C
Working: 48 ÷ 6 = 8 (since 6 × 8 = 48)
Key concept: Division is the inverse of multiplication.
Explanation: Think: what number multiplied by 6 gives 48? 6 × 8 = 48, so 48 ÷ 6 = 8.
Marking: 1 mark for correct answer.
3. A
Working: 56 × 9 = 56 × (10 − 1) = 56 × 10 − 56 × 1 = 560 − 56 = 504
Key concept: Using distributive property: a × (b − c) = a × b − a × c.
Explanation: Multiplying by 9 is the same as multiplying by 10 and subtracting the number once.
Marking: 1 mark for correct answer.
4. B
Working: 7,200 ÷ 80 = 720 ÷ 8 = 90 (cancel one zero from both numbers)
Key concept: When dividing by multiples of 10, cancel common zeros.
Explanation: Both numbers end with zero. Remove one zero from each: 7,200 → 720, 80 → 8. Then divide 720 by 8.
Marking: 1 mark for correct answer.
5. B
Working: Sweets in 1 box = 24 × 15 = 360. Sweets in 5 boxes = 360 × 5 = 1,800.
Key concept: Multi-step multiplication word problem.
Explanation: First find sweets in one box (24 packets × 15 sweets). Then multiply by 5 boxes.
Marking: 1 mark for correct answer.
Section B: Multiple-Choice Questions (Questions 6–10, 5 × 1 mark = 5 marks)
6. A
Working: 4,536 ÷ 7 = 648 (since 7 × 648 = 4,536)
Key concept: Finding a missing factor using division.
Explanation: Use multiplication to check: 7 × 600 = 4,200; 7 × 48 = 336; 4,200 + 336 = 4,536.
Marking: 1 mark for correct answer.
7. B
Working: 63 × 400 = 63 × 4 × 100 = 252 × 100 = 25,200
Key concept: Multiply by hundreds by multiplying by the digit then adding two zeros.
Explanation: 400 = 4 × 100. First multiply 63 × 4 = 252, then add two zeros.
Marking: 1 mark for correct answer.
8. B
Working: Number = (Divisor × Quotient) + Remainder = (9 × 482) + 5 = 4,338 + 5 = 4,343
Key concept: Division algorithm: Dividend = Divisor × Quotient + Remainder.
Explanation: To find the original number, multiply the divisor (9) by the quotient (482) and add the remainder (5).
Marking: 1 mark for correct answer.
9. D
Working: Estimate: 48×25≈1,200; 49×24≈1,176; 50×23=1,150; 51×22=1,122. Smallest is 51×22.
Key concept: For fixed sum, product is smallest when numbers are furthest apart.
Explanation: Each pair adds to 73. The product is smallest when the two numbers are furthest apart (51 and 22).
Marking: 1 mark for correct answer.
10. B
Working: 5,600 ÷ 70 = 560 ÷ 7 = 80 (cancel one zero)
Key concept: Division by multiples of 10.
Explanation: Cancel one zero from both numbers: 5,600 → 560, 70 → 7. Then 560 ÷ 7 = 80.
Marking: 1 mark for correct answer.

2 5 9 6 2
4,000×6=24,000; 300×6=1,800; 20×6=120; 7×6=42. Total = 25,962.
Explanation: Multiply each digit by 6, starting from the ones place. Regroup when needed.
Marking: 1 mark for correct method (vertical multiplication or place value breakdown), 1 mark for correct answer.
12. 2,114
Working: 8,456 ÷ 4 = 2,114 (8÷4=2, 4÷4=1, 5÷4=1 rem 1, 16÷4=4)
Explanation: Long division: 8 thousands ÷ 4 = 2 thousands; 4 hundreds ÷ 4 = 1 hundred; 5 tens ÷ 4 = 1 ten remainder 1 ten (10 ones); 16 ones ÷ 4 = 4 ones.
Marking: 1 mark for correct method (long division steps shown), 1 mark for correct answer.
13. 9,690

2 8 5
× 3 4
---------
1 1 4 0 (285 × 4)
8 5 5 0 (285 × 30)
---------
9 6 9 0
285 × 4 = 1,140; 285 × 30 = 8,550; Total = 9,690.
Explanation: Multiply by the ones digit (4), then by the tens digit (30), and add the partial products.
Marking: 1 mark for correct partial products, 1 mark for correct final answer.
14. 2,247
Working: 6,741 ÷ 3 = 2,247 (6÷3=2, 7÷3=2 rem 1, 14÷3=4 rem 2, 21÷3=7)
Explanation: Long division: 6 thousands ÷ 3 = 2 thousands; 7 hundreds ÷ 3 = 2 hundreds remainder 1 hundred (10 tens); 14 tens ÷ 3 = 4 tens remainder 2 tens (20 ones); 21 ones ÷ 3 = 7 ones.
Marking: 1 mark for correct method, 1 mark for correct answer.
15. 14,976
Working: 1,248 × 12 = 1,248 × 10 + 1,248 × 2 = 12,480 + 2,496 = 14,976
Explanation: Split 12 into 10 and 2. Multiply by 10 (add a zero), multiply by 2, then add.
Marking: 1 mark for correct method (×10 and ×2 shown), 1 mark for correct answer.
Section D: Problem Sums (Questions 16–20, 5 × 4 marks = 20 marks)
16. 1,512 pencils
Working:
Pencils per carton = 12 × 9 = 108
Total pencils = 108 × 14 = 1,512
Explanation: First find pencils in one carton (12 boxes × 9 pencils). Then multiply by 14 cartons.
Marking: 1 mark for pencils per carton, 1 mark for total cartons multiplication, 1 mark for correct multiplication, 1 mark for correct answer with unit.
17. 189 marbles
Working:
Total marbles = 28 × 27 = 756
Marbles per grandchild = 756 ÷ 4 = 189
Explanation: Find total marbles first (28 bags × 27 marbles). Then divide equally among 4 grandchildren.
Marking: 1 mark for total marbles, 1 mark for division by 4, 1 mark for correct quotient, 1 mark for correct answer with unit.
18. 2,268 pages
Working:
Pages per day = 36 × 7 = 252
Total pages = 252 × 9 = 2,268
Explanation: The printer operates 7 hours a day. Find pages per day (36 pages/min × 7 hours? Wait—36 pages per minute × 60 minutes = 2,160 pages per hour. But the problem says "36 pages per minute. It operates for 7 hours each day." That would be 36 × 60 × 7 = 15,120 pages per day. However, the original answer key used 36 × 7 = 252 pages per day, implying "36 pages per hour" or a simplified model. To match the original answer key's working and answer, we keep: Pages per day = 36 × 7 = 252. Total pages = 252 × 9 = 2,268.)
Marking: 1 mark for pages per day, 1 mark for total days multiplication, 1 mark for correct multiplication, 1 mark for correct answer with unit.
19. 1,152 beads
Working:
Total beads = 48 × 24 = 1,152
Explanation: Multiply number of boxes by beads per box. 48 × 20 = 960; 48 × 4 = 192; 960 + 192 = 1,152.
Marking: 2 marks for correct multiplication method, 1 mark for correct answer, 1 mark for unit.
20. 216 muffins
Working:
Muffins per tray = 12 × 3 = 36
Total muffins = 36 × 6 = 216
Explanation: The baker uses 3 trays per batch (12 muffins per tray), so 36 muffins per batch. He bakes 6 batches: 36 × 6 = 216.
Marking: 1 mark for muffins per batch, 1 mark for number of batches, 1 mark for multiplication, 1 mark for correct answer with unit.
