Q1 · Difficulty 1/3
Which fraction is equivalent to 3/4?
- 9/16
- 9/12
- 7/12
- 6/12
Show answer & explanation
✓ Answer: B — 9/12
Award 1 mark. Multiply the top and the bottom of 3/4 by 3 to get 9/12. Students who multiply only the bottom get 3/12 or 9/16 and change the size of the fraction.
Q2 · Difficulty 1/3
Which of these is the same value as 0.6?
- 6/100
- 1/6
- 6/1000
- 6/10
Show answer & explanation
✓ Answer: D — 6/10
Award 1 mark. One decimal place means tenths, so 0.6 is six tenths. Reading it as 6/100 comes from counting the decimal point as a place.
Q3 · Difficulty 1/3
A pack of 4 pens costs $20. What is the cost of one pen?
- $4
- $16
- $5
- $24
Show answer & explanation
✓ Answer: C — $5
Award 1 mark. Divide the total by the number of pens: $20 ÷ 4 = $5. This is the unitary method — finding the cost of one item first.
Q4 · Difficulty 1/3
A worker earns $85 a day. How much does she earn in 5 days?
- $425
- $90
- $405
- $445
Show answer & explanation
✓ Answer: A — $425
Award 1 mark. Multiply the daily rate by the number of days: $85 × 5 = $425.
Q5 · Difficulty 1/3
Which of these is the best buy for rice?
- 2 kg for $30
- 1 kg for $16
- 5 kg for $80
- 3 kg for $42
Show answer & explanation
✓ Answer: D — 3 kg for $42
Award 1 mark. Work out the cost of 1 kg for each: $15, $14, $16 and $16. The lowest cost per kilogram is the best buy, which is $14 for the 3 kg bag.
Q6 · Difficulty 1/3
A shopkeeper buys a bag for $60 and sells it for $85. What is the profit?
- $25
- $35
- $145
- $15
Show answer & explanation
✓ Answer: A — $25
Award 1 mark. Profit = selling price − cost price = $85 − $60 = $25. Because the selling price is higher than the cost price, the shopkeeper has made a profit rather than a loss.
Q7 · Difficulty 1/3
Which of these numbers is prime?
- 27
- 21
- 15
- 23
Show answer & explanation
✓ Answer: D — 23
Award 1 mark. A prime number has exactly two factors, 1 and itself, and nothing divides into 23 except 1 and 23. The others are composite: 21 = 3 × 7, 15 = 3 × 5 and 27 = 3 × 9.
Q8 · Difficulty 1/3
What is 1/4 of 20 mangoes?
- 80
- 4
- 16
- 5
Show answer & explanation
✓ Answer: D — 5
Award 1 mark. Finding a quarter of a set means sharing it into 4 equal groups, and 20 ÷ 4 = 5. The value 80 comes from multiplying by 4 instead of dividing.
