Primary 6 PSLE Mathematics Quiz - Multiplication Division: Answer Key

Version: 1 of 5 | Total Marks: 60 | Duration: 60 minutes

Marking guidance: Award method (M) marks for correct strategy even if a slip occurs late; award answer (A) marks for accurate, correctly-united final answers.

Answer 1.

Answer: 9342 (2 marks)

Concept: Split 27 into $20 + 7$ and multiply each part.
$346 \times 20 = 6920$
$346 \times 7 = 2422$
$6920 + 2422 = 9342$
Check: $9342 \div 27 = 346$ . ✓
Marking: M1 for correct partial products/column method, A1 for 9342.
Common mistake: Misaligning place values when adding partial products.

Answer 2.

Answer: 508 (2 marks)

Concept: Long division, one digit-place at a time.
$81 \div 16 = 5$ remainder $1$ ; bring down 2 → $12 \div 16 = 0$ remainder $12$ (write the 0); bring down 8 → $128 \div 16 = 8$ .
Quotient: 508. Check: $508 \times 16 = 8128$ . ✓
Marking: M1 for structured long division, A1 for 508.
Common mistake: Omitting the zero in the tens place, giving 58.

Answer 3.

Answer: 48 (2 marks)

Concept: Order of operations — do $\div$ and $\times$ first, working left to right, then $+$ .
$36 \div 6 = 6$ ; then $6 \times 4 = 24$ ; then $24 + 24 = 48$ .
Marking: M1 for correct order of operations, A1 for 48.
Common mistake: Adding first ( $24 + 36 = 60$ ), which gives a wrong result.

Answer 4.

Answer: 150 (2 marks)

Method: $3.75 \times 40 = 375 \times 40 \div 100 = 15000 \div 100 = 150$ .
Alternative: $3.75 \times 4 = 15$ , then $\times 10 = 150$ .
Marking: M1 for valid method, A1 for 150.
Common mistake: Placing the decimal point wrongly (e.g., 15.00 vs 150).

Answer 5.

Answer: 3.6 (2 marks)

Method: $17 \times 3 = 51$ , remainder $10.2$ . Place the decimal point, then $102$ tenths $\div 17 = 6$ tenths.
Result: $3.6$ . Check: $17 \times 3.6 = 61.2$ . ✓
Marking: M1 for correct division process, A1 for 3.6.

Answer 6.

Answer: 42 (2 marks)

Concept: Multiplication and division are inverse operations, so the missing factor is found by dividing.
$1890 \div 45 = 42$ .
Check: $45 \times 42 = 1890$ . ✓
Marking: M1 for dividing 1890 by 45, A1 for 42.

Answer 7.

Answer: 10 000 (2 marks)

Concept: Rounding makes numbers friendly for mental estimation.
$498 \approx 500$ (nearest ten); $21 \approx 20$ (nearest ten).
Estimate: $500 \times 20 = 10\,000$ .
Marking: M1 for both correct roundings, A1 for 10 000.
Note: The exact value 10 458 is close to the estimate, showing the estimate is reasonable.

Answer 8.

Answer: 2148 and 4728 (2 marks)

Concept: Divisible by both 3 and 4 means divisible by 12.
Test for 3 (digit sum divisible by 3): 2148 → 15 ✓; 3150 → 9 ✓; 4728 → 21 ✓; 5310 → 9 ✓.
Test for 4 (last two digits divisible by 4): 48 ✓; 50 ✗; 28 ✓; 10 ✗.
Only 2148 and 4728 pass both tests.
Marking: A2 for both correct; A1 for one correct with evidence of testing.

Answer 9.

Answer: 7 buses (2 marks)

$250 \div 40 = 6$ remainder $10$ .
Six buses seat only 240 pupils, so the remaining 10 pupils still need a bus.
Smallest number of buses: $6 + 1 = 7$ .
Marking: M1 for division with remainder, A1 for 7.
Common mistake: Answering 6 — always round up for grouping real people/objects.

Answer 10.

Answer: 99 stickers (2 marks)

Concept: Use units. Ravi has 1 unit; Mei has 3 units.
Total: $1u + 3u = 4u = 132$ , so $1u = 132 \div 4 = 33$ .
Mei: $3 \times 33 = 99$ stickers.
Marking: M1 for unit model or equation, A1 for 99.
Common mistake: Giving 33 (Ravi's amount) instead of Mei's.

Answer 11.

Answer: $45.50 (3 marks)

Step 1 (unit cost): $26 \div 8 = \$ 3.25$ per notebook.
Step 2 (scale up): $3.25 \times 14 = \$ 45.50$.
Concept: Unitary method — find the value of one item first, then multiply.
Marking: M1 for $26 \div 8$ , A1 for $3.25$ , A1 for final $45.50 with$ sign.

Answer 12.

Answer: 1012 pages (3 marks)

Step 1 (rate): $345 \div 15 = 23$ pages per minute.
Step 2 (total): $23 \times 44 = 1012$ pages.
Concept: Rate = total ÷ time; new total = rate × new time.
Marking: M1 for finding rate, A1 for 23 pages/min, A1 for 1012 pages.

Answer 13.

Answer: 24 full boxes, 120 tarts left over (3 marks)

Step 1: $6000 \div 245$ . Since $245 \times 24 = 5880$ , quotient is 24.
Step 2: Leftover $= 6000 - 5880 = 120$ tarts.
Concept: The quotient gives complete groups; the remainder is what cannot fill another box.
Marking: M1 for division setup, A1 for 24 boxes, A1 for 120 tarts.
Common mistake: Rounding the quotient instead of reporting quotient and

Marking: M1 for $756 \div 21$ , A1 for 36, A1 for 57.

Answer 15.

Answer: 81 chairs in 9 rows (3 marks)

A square array needs a perfect square: rows × columns with equal values.
Perfect squares between 80 and 100: only $81 = 9 \times 9$ ( $64$ and $100$ fall outside the range).
So there are 81 chairs arranged in 9 rows of 9.
Marking: M1 recognising a square number is needed, A1 for 81, A1 for 9 rows.

Answer 16.

Answer: $40 spent; 2 extra pens (4 marks)

Step 1: $58 \div 6 = 9$ remainder $4$ , so 9 packs give only 54 pens — not enough.
Step 2: She must buy $10$ packs: $10 \times 6 = 60$ pens.
Cost: $10 \times \$ 4 = $40 $. Extra pens:$ 60 - 58 = 2$.
Marking: M1 rounding up to 10 packs, A1 cost $40, A1 extra 2 pens, A1 working/units.
Common mistake: Buying 9 packs ($36) — insufficient pens.

Answer 17.

Answer: 116 more ducks (4 marks)

Units: chickens = 1 unit, ducks = 5 units; total $6u = 174$ , so $1u = 174 \div 6 = 29$ .
Ducks $= 5 \times 29 = 145$ ; chickens $= 29$ .
Difference: $145 - 29 = 116$ .
Marking: M1 model/equation, A1 for 29 (or 145), A1 difference 116, A1 working.
Common mistake: Finding counts but forgetting to subtract.

Answer 18.

Answer: 15 (4 marks)

Reverse each step: final answer 25 → multiply by 7: $25 \times 7 = 175$ .
Add back 35: $175 + 35 = 210$ .
Divide by 14: $210 \div 14 = 15$ .
Check forward: $15 \times 14 = 210$ ; $210 - 35 = 175$ ; $175 \div 7 = 25$ . ✓
Marking: M1 reversing steps, A1 for 175, A1 for 210, A1 for 15.

Answer 19.

(a) Answer: 150 mL (b) Answer: 30 cups (4 marks)

(a) $2.4$ litres $= 2400$ mL; $2400 \div 16 = 150$ mL per cup.
(b) $4.5$ litres $= 4500$ mL; $4500 \div 150 = 30$ cups exactly, so 30 cups can be filled completely.
Marking: (a) M1 conversion to mL, A1 for 150 mL; (b) M1 division by cup size, A1 for 30.
Common mistake: Dividing litres directly without converting to millilitres.

Answer 20.

Answer: 68 pages per chapter (5 marks)

Step 1 (time): 10:45 to 11:05 = 20 minutes.
Step 2 (total pages): $38 \times 20 = 760$ pages.
Step 3 (chapter pages): $760 - 12 = 748$ pages for the 11 chapters.
Step 4: $748 \div 11 = 68$ pages per chapter.
Check: $(11 \times 68) + 12 = 748 + 12 = 760$ . ✓
Marking: M1 time elapsed, A1 for 760, M1 subtracting photo section, A1/M1 for $748 \div 11$ , A1 for 68.
Common mistake: Forgetting to remove the 12-page photo section before dividing.
