Primary 6 PSLE Mathematics Quiz - Multiplication Division (Answer Key)

Total Marks: 40
Topic: Multiplication Division

---

Section A — Direct Calculation (2 marks each)

1. $48 \times 6 = 288$
Working: $40 \times 6 = 240$, $8 \times 6 = 48$, $240 + 48 = 288$.
Teaching note: Multiplication is repeated addition. Breaking into tens and ones helps avoid mistakes.

2. $144 \div 12 = 12$
Working: $12 \times 12 = 144$, so quotient is $12$.
Teaching note: Division is the inverse of multiplication.

3. $\frac{2}{3} \times 9 = \frac{2 \times 9}{3} = \frac{18}{3} = 6$
Teaching note: Multiply numerator by whole number, then divide by denominator.

4. $5 \div \frac{1}{2} = 5 \times 2 = 10$
Teaching note: Dividing by a fraction means multiplying by its reciprocal. "How many halves in 5?" → 10.

5. $8 \times 15 = 120$ marbles
Working: $8 \times 10 = 80$, $8 \times 5 = 40$, $80 + 40 = 120$.
Teaching note: Total = number of packets × items per packet.

---

Section B — Fractions and Decimals (2 marks each)

6. $\frac{3}{4} \times \frac{2}{5} = \frac{3 \times 2}{4 \times 5} = \frac{6}{20} = \frac{3}{10}$
Teaching note: Multiply numerators and denominators, then simplify.

7. $2\frac{1}{2} \div \frac{1}{4} = \frac{5}{2} \times 4 = \frac{20}{2} = 10$
Teaching note: Convert mixed number to improper fraction, then multiply by reciprocal.

8. $3.6 \div 0.4 = 36 \div 4 = 9$ pieces
Teaching note: Multiply both by 10 to remove decimal, then divide.

9. $0.25 \times 8 = 2.00$ (or $2$)
Working: $25 \times 8 = 200$, shift decimal two places → $2.00$.
Teaching note: $0.25$ is a quarter; $4 \times 0.25 = 1$, so $8 \times 0.25 = 2$.

10. $\frac{5}{8} \div 5 = \frac{5}{8} \times \frac{1}{5} = \frac{1}{8}$
Teaching note: Dividing by whole number = multiply by unit fraction.

Section C — Word Problems (3 marks each)

11. Stickers left = $36 - \frac{1}{3} \times 36 = 36 - 12 = 24$.
Marks: 1 for finding given amount (12), 2 for final answer 24.
Teaching note: Find the part given, then subtract from whole.

12. Total = $7 \times 10 = 70$; left = $70 - 25 = 45$ notebooks.
Marks: 1 for total, 2 for remainder.
Teaching note: Multiply packs by pack size, then subtract used.

13. Batches = $6 \div \frac{3}{4} = 6 \times \frac{4}{3} = 8$ batches.
Marks: 2 for reciprocal method, 1 for answer.
Teaching note: Number of groups = total ÷ per group.

14. Total = $42 \times 6 = 252$; per group = $252 \div 9 = 28$.
Marks: 1.5 each part.
Teaching note: Two-step: multiply then divide.

15. Days = $192 \div 24 = 8$ days.
Marks: 3 for correct division.
Teaching note: Total pages ÷ pages per day = days.

16. Papaya = $2.4 \div 3 = 0.8$ kg.
Marks: 3 for division.
Teaching note: "3 times as heavy" → divide by 3 to find 1 unit.

17. Toys = $125 \times 8 = 1000$; boxes = $1000 \div 25 = 40$.
Marks: 1.5 each.
Teaching note: Multiply for total, divide by box capacity.

18. Used for cake = $\frac{1}{5} \times 3 = 0.6$ kg; remainder = $3 - 0.6 = 2.4$ kg; used for bread = $\frac{2}{5} \times 2.4 = 0.96$ kg; left = $2.4 - 0.96 = 1.44$ kg.
Marks: 1 for first step, 1 for second, 1 for final.
Teaching note: Track changing remainder carefully.

19. Pieces = $12 \div 0.75 = 1200 \div 75 = 16$; used = $4 \times 0.75 = 3$ m; remain = $12 - 3 = 9$ m.
Marks: 1.5 each.
Teaching note: Convert to integers if needed; subtract used length.

20. Groups = $40 \div 5 = 8$; cans = $8 \times 8 = 64$; given = $3 \times 10 = 30$; remain = $64 - 30 = 34$.
Marks: 1 for groups, 1 for total cans, 1 for remainder.
Teaching note: Multi-step: divide, multiply, subtract.
