QTS Numeracy Skills for Teachers 1 — Questions and Answers
Question 1: What is 4.7 × 100?
- 470 (Correct answer)
- 47
- 4700
- 0.47
Correct answer: 470
Multiplying by 100 moves each digit two places to the left, so 4.7 becomes 470.
Question 2: A class of 28 pupils has 75% achieving the expected standard. How many pupils is that?
- 21 (Correct answer)
- 14
- 24
- 7
Correct answer: 21
75% of 28 = 0.75 × 28 = 21 pupils. Alternatively, 75% is three-quarters, and three-quarters of 28 is 21.
Question 3: What is the mean of the following test scores: 56, 72, 68, 84, 60?
- 68 (Correct answer)
- 66
- 70
- 72
Correct answer: 68
Sum = 56 + 72 + 68 + 84 + 60 = 340. Mean = 340 ÷ 5 = 68.
Question 4: Convert 3/8 to a decimal.
- 0.375 (Correct answer)
- 0.38
- 0.3
- 0.4
Correct answer: 0.375
3 ÷ 8 = 0.375. Alternatively, 1/8 = 0.125, so 3/8 = 3 × 0.125 = 0.375.
Question 5: A teacher records that 12 out of 30 pupils need additional support. What percentage is this?
- 40% (Correct answer)
- 30%
- 36%
- 42%
Correct answer: 40%
12 ÷ 30 = 0.4, which is 40%. Alternatively, 12/30 simplifies to 2/5 = 40%.
Question 6: What is 15% of 240?
- 36 (Correct answer)
- 24
- 48
- 30
Correct answer: 36
10% of 240 = 24. 5% of 240 = 12. So 15% = 24 + 12 = 36.
