NAPLAN Numeracy Skills 2 — Questions and Answers
Question 1: A Year 9 NAPLAN student is asked to solve: 5x − 3 = 22. What is the value of x?
- 5 (Correct answer)
- 4
- 6
- 3
Correct answer: 5
5x = 22 + 3 = 25, so x = 25 ÷ 5 = 5.
Question 2: In NAPLAN Numeracy, students are expected to convert between fractions, decimals, and percentages. What is 0.65 expressed as a percentage?
- 65% (Correct answer)
- 6.5%
- 0.65%
- 650%
Correct answer: 65%
To convert a decimal to a percentage, multiply by 100, so 0.65 × 100 = 65%.
Question 3: A NAPLAN question shows a bar graph of student test scores. If 8 students scored between 70–79 and 12 students scored between 80–89, how many students scored in those two ranges combined?
- 20 (Correct answer)
- 16
- 18
- 22
Correct answer: 20
8 + 12 = 20 students scored in the 70–79 and 80–89 ranges combined.
Question 4: Which of the following best describes the purpose of the non-calculator section in the NAPLAN Numeracy test?
- To assess mental computation and number sense without technological aids (Correct answer)
- To test students' ability to use calculator functions effectively
- To evaluate only geometry and measurement skills
- To allow students extra time for complex problems
Correct answer: To assess mental computation and number sense without technological aids
The non-calculator section assesses students' ability to perform mental computations and demonstrates their fundamental number sense.
Question 5: A Year 5 NAPLAN question asks: 'What is the perimeter of a square with side length 9 cm?' What is the correct answer?
- 36 cm (Correct answer)
- 18 cm
- 81 cm
- 27 cm
Correct answer: 36 cm
The perimeter of a square = 4 × side length = 4 × 9 = 36 cm.
Question 6: In NAPLAN, which year levels are assessed in the Numeracy test?
- Years 3, 5, 7, and 9 (Correct answer)
- Years 4, 6, 8, and 10
- Years 3, 6, and 9
- Years 5, 7, and 9
Correct answer: Years 3, 5, 7, and 9
NAPLAN assesses students in Years 3, 5, 7, and 9 across all domains including Numeracy.
Question 7: A NAPLAN Year 7 question asks students to find the median of the dataset: 4, 7, 3, 9, 5. What is the median?
- 5 (Correct answer)
- 4
- 7
- 6
Correct answer: 5
Ordering the data gives 3, 4, 5, 7, 9 — the middle value (median) is 5.
