Primary 5 Mathematics Quiz - Multiplication Division: Answer Key

Total Marks: 40 | Section A: 5 | Section B: 20 | Section C: 15

Answer 1.

Answer: 473 500 (1 mark) Multiplying by 100 shifts every digit two places to the left (each digit becomes 100 times larger): 4 735 → 473 500. Common mistake: adding only one zero (47 350). Always match the number of zeros to the multiplier.

Answer 2.

Answer: 82 (1 mark) Dividing by 1000 shifts every digit three places to the right: 82 000 → 82. Check: 82 × 1000 = 82 000. ✓

Answer 3.

Answer: 64 (1 mark) Order of operations: multiply before add. Step 1: 8 × 5 = 40. Step 2: 24 + 40 = 64. Common mistake: working left to right gives (24 + 8) × 5 = 160, which is wrong.

Answer 4.

Answer: 708 (1 mark) Multiplying a decimal by 100 moves the decimal point two places right: 7.08 → 708. Common mistake: 70.8 (moving only one place).

Answer 5.

Answer: 50 (1 mark) Division undoes multiplication, so the missing number is 1 800 ÷ 36 = 50. Check: 36 × 50 = 1 800. ✓

Answer 6.

Answer: 75 (2 marks) Order of operations (brackets → × ÷ → + −):

Step 1 (brackets): 36 ÷ 4 = 9
Step 2 (multiplication): 9 × 5 = 45
Step 3 (subtraction): 120 − 45 = 75

Marking: 1 mark for correct order/steps, 1 mark for final answer 75. Common mistake: subtracting first: (120 − 36) ÷ 4 × 5 = 105.

Answer 7.

Answer: 10 948 (2 marks) Column method — split 46 into 40 and 6:

238 × 6 = 1 428
238 × 40 = 9 520
Add: 1 428 + 9 520 = 10 948

Marking: 1 mark for both partial products correct, 1 mark for correct total.

Answer 8.

Answer: 728 (2 marks) Long division:

8 × 700 = 5 600; 5 824 − 5 600 = 224 remaining
8 × 28 = 224; remainder 0
Quotient = 728

Check: 728 × 8 = 5 824. ✓ Marking: 1 mark for method/steps, 1 mark for 728 with no remainder.

Answer 9.

Answer: 3 000 boxes (2 marks) Total boxes = rate × time = 250 × 12. Break it up: 250 × 10 = 2 500 and 250 × 2 = 500; 2 500 + 500 = 3 000. Marking: 1 mark for correct multiplication, 1 mark for answer with units.

Answer 10.

Answer: 503 beads (2 marks) Equal sharing means divide: 4 527 ÷ 9.

9 × 500 = 4 500; 4 527 − 4 500 = 27 left
27 ÷ 9 = 3
Each pupil gets 503 beads.

Check: 503 × 9 = 4 527. ✓ Marking: 1 mark for division method, 1 mark for 503.

Answer 11.

Answer: 35 (2 marks) "of" means multiply. To find $\frac{5}{6}$ of 42:

Step 1: find one sixth: 42 ÷ 6 = 7
Step 2: take five sixths: 7 × 5 = 35

Marking: 1 mark for dividing by the denominator, 1 mark for multiplying by the numerator (35).

Answer 12.

Answer: $\frac{5}{6}$ m (2 marks) Cutting 5 m into 6 equal pieces means 5 ÷ 6, which is written as the fraction $\frac{5}{6}$ . Each piece is five-sixths of a metre. The fraction is already in simplest form. Common mistake: writing $\frac{6}{5}$ (inverting the numbers). Remember: what you share goes on top.

Answer 13.

Answer: 3 750 g (2 marks) 1 kg = 1 000 g, so multiply by 1000: move the decimal point three places right. 3.75 → 3 750 g. Marking: 1 mark for knowing ×1000, 1 mark for 3 750 g with units. Common mistake: 37.5 g (moving only one place).

Answer 14.

Answer: 10 200 (2 marks) Mental method: 340 = 34 × 10 and 30 = 3 × 10, so there are two extra tens overall.

Step 1: 34 × 3 = 102
Step 2: attach two zeros (one from each ten): 102 → 10 200

Alternative: 340 × 3 = 1 020, then × 10 = 10 200. Marking: 1 mark for a clear place-value explanation, 1 mark for 10 200.

Answer 15.

Answer: 880 stickers (2 marks)

Step 1 (total stickers): 48 × 25 = 1 200. Shortcut: 48 × 25 = 48 × 100 ÷ 4 = 4 800 ÷ 4 = 1 200.
Step 2 (after selling): 1 200 − 320 = 880

Marking: 1 mark for 1 200 total, 1 mark for 880 left.

Answer 16.

Answer: 83 full boxes, 80 buttons left unpacked (3 marks)

Step 1 (total made): 1 250 × 16 = 20 000 buttons
Step 2 (divide into boxes): 20 000 ÷ 240 = 83 remainder 80, because 240 × 83 = 19 920 and 20 000 − 19 920 = 80
Step 3 (interpret): 83 completely filled boxes; the remaining 80 buttons cannot fill another box.

Marking: 1 mark for 20 000, 1 mark for division with correct remainder, 1 mark for both interpreted values with units.

Answer 17.

Answer: $920 (3 marks) Think of her money as one bar split into two parts: money spent on chairs + money left.

Step 1 (money spent): 8 × $96 = $768
Step 2 (money at first): $768 + $152 = $920

Check: $920 − $768 = $152 left. ✓ Marking: 1 mark for 768, 1 mark for adding the leftover, 1 mark for $920 with units. Common mistake: subtracting 152 instead of adding it.

Answer 18.

Answer: 7 buses (3 marks)

Step 1 (divide): 275 ÷ 40 = 6 remainder 35, since 40 × 6 = 240 and 275 − 240 = 35
Step 2 (reason): 6 buses carry only 240 pupils, leaving 35 pupils without seats.
Step 3 (conclude): those 35 pupils still need a whole bus, so round up: 7 buses.

Marking: 1 mark for correct division with remainder, 1 mark for explaining the remainder must not be discarded, 1 mark for concluding 7 buses. Common mistake: answering 6 (rounding down) or 6
