QTS Numeracy Skills for Teachers 1

Question 1

What is 4.7 × 100?

Accepted Answer

470

Answer

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?

Accepted Answer

21

Answer

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?

Accepted Answer

68

Answer

Sum = 56 + 72 + 68 + 84 + 60 = 340. Mean = 340 ÷ 5 = 68.

Question 4

Convert 3/8 to a decimal.

Accepted Answer

0.375

Answer

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?

Accepted Answer

40%

Answer

12 ÷ 30 = 0.4, which is 40%. Alternatively, 12/30 simplifies to 2/5 = 40%.
