Answers

Primary 6 PSLE Mathematics Quiz - Fractions (Answer Key)

Total Marks: 40
Topic: Fractions

Section A: Answers 1–5 (2 marks each)

1. $\frac{3}{8}$
Working: $\frac{3}{4} \div 2 = \frac{3}{4} \times \frac{1}{2} = \frac{3}{8}$ .
Teaching note: Dividing by a whole number means multiply by its reciprocal (flip the whole number to $\frac{1}{2}$ ).

2. $15$
Working: $5 \div \frac{1}{3} = 5 \times 3 = 15$ .
Teaching note: "How many thirds in 5?" Each whole has 3 thirds, so $5 \times 3 = 15$ .

3. $\frac{4}{5}$
Working: $\frac{2}{5} \div \frac{1}{2} = \frac{2}{5} \times \frac{2}{1} = \frac{4}{5}$ .
Teaching note: Reciprocal of $\frac{1}{2}$ is $\frac{2}{1}$ .

4. $\frac{2}{3}$
Working: $1 - \frac{1}{3} = \frac{3}{3} - \frac{1}{3} = \frac{2}{3}$ .
Teaching note: Whole cake = 1.

5. $6$
Working: $1\frac{1}{2} = \frac{3}{2}$ ; $\frac{3}{2} \div \frac{1}{4} = \frac{3}{2} \times 4 = 6$ .
Teaching note: Convert mixed number to improper fraction first.

Section B: Answers 6–10 (2 marks each)

6. $3$ L
Working: $12 \times \frac{1}{4} = 3$ .

7. $20$
Working: Given $= 24 \times \frac{1}{6} = 4$ ; left $= 24 - 4 = 20$ .

8. $48$
Working: $120 \times \frac{2}{5} = 48$ .

9. $12$
Working: $8 \div \frac{2}{3} = 8 \times \frac{3}{2} = 12$ .

10. $7$ kg
Working: Used $= 10 \times \frac{3}{10} = 3$ ; left $= 10 - 3 = 7$ .

Section C: Answers 11–20

11. (2 marks) $\frac{1}{2}$
Working: Spent $\frac{1}{2}$ , left $\frac{1}{2}$ . Of remainder spent $\frac{1}{3} \times \frac{1}{2} = \frac{1}{6}$ . Total spent $= \frac{1}{2} + \frac{1}{6} = \frac{2}{3}$ . Left $= 1 - \frac{2}{3} = \frac{1}{3}$ ? Wait: remainder after toy = $\frac{1}{2}$ . Book = $\frac{1}{3}$ of $\frac{1}{2}$ = $\frac{1}{6}$ . Left = $\frac{1}{2} - \frac{1}{6} = \frac{1}{3}$ .
Correction: Answer is $\frac{1}{3}$ .
Teaching note: Track remainder carefully.

12. (2 marks) $30$
Working: Boys $= 40 \times \frac{1}{4} = 10$ ; girls $= 40 - 10 = 30$ .

13. (2 marks) $30$
Working: $\frac{3}{5} \rightarrow 18$ , so $\frac{1}{5} \rightarrow 6$ , total $= 5 \times 6 = 30$ .

14. (4 marks) $\$ 48$
Mark breakdown: 2 marks for correct fractions, 2 marks for final answer.
Working:

After food: remainder $= 1 - \frac{1}{3} = \frac{2}{3}$ .
Transport $= \frac{1}{4} \times \frac{2}{3} = \frac{1}{6}$ .
Left fraction $= \frac{2}{3} - \frac{1}{6} = \frac{1}{2}$ .
$\frac{1}{2}$ of original $= 28 \Rightarrow$ original $= 56$ ? Wait: $\frac{2}{3} - \frac{1}{6} = \frac{4}{6} - \frac{1}{6} = \frac{3}{6} = \frac{1}{2}$ . So $28$ is $\frac{1}{2}$ , original $= 56$ .
Correction: Answer $\$ 56$.
Teaching note: Backward fraction tracking.

15. (4 marks) $\$ 300$
Working:

Books $= \frac{2}{5}$ , remainder $= \frac{3}{5}$ .
Chairs $= \frac{1}{2} \times \frac{3}{5} = \frac{3}{10}$ .
Left $= \frac{3}{5} - \frac{3}{10} = \frac{3}{10}$ .
$\frac{3}{10} \rightarrow 90 \Rightarrow \frac{1}{10} \rightarrow 30 \Rightarrow$ total $= 300$ .

16. (2 marks) $\frac{3}{4}$
Working: $\frac{3}{4} = \frac{6}{8} > \frac{5}{8}$ .

17. (4 marks) $45$
Working: Let Tom = $x$ , Sam = $\frac{2}{3}x$ .
$\frac{2}{3}x + 10 = x - 5$
$10 + 5 = x - \frac{2}{3}x$
$15 = \frac{1}{3}x \Rightarrow x = 45$ .

18. (4 marks) $\frac{1}{2}$ m
Working: Curtain $= \frac{1}{2} \times 3 = 1.5$ m; remainder $= 1.5$ m. Tablecloth $= \frac{2}{3} \times 1.5 = 1$ m. Left $= 1.5 - 1 = 0.5$ m $= \frac{1}{2}$ m.

19. (4 marks) $60$
Working: Monday left $= \frac{2}{3}$ . Tuesday sold $\frac{1}{2} \times \frac{2}{3} = \frac{1}{3}$ . Left $= \frac{2}{3} - \frac{1}{3} = \frac{1}{3}$ . $\frac{1}{3} \rightarrow 20 \Rightarrow$ total $= 60$ .

20. (4 marks) $\$ 960 $*Working:* Rent$ = \frac{1}{4} $, remainder$ = \frac{3}{4} $. Food$ = \frac{1}{3} \times \frac{3}{4} = \frac{1}{4} $. Saved$ = \frac{3}{4} - \frac{1}{4} = \frac{1}{2} $.$ \frac{1}{2} \rightarrow 600 \Rightarrow $salary$ = 1200 $? Wait:$ \frac{3}{4} - \frac{1}{4} = \frac{2}{4} = \frac{1}{2} $. So$ 600 $is$ \frac{1}{2} $, salary$ = 1200 $. *Correction:* Answer$ $1200$.
