Question

12 In a 2 1/2 hour maths exam, 1/6 of that time is allocated as reading time. How long is the reading time?

Answer 1

5/12 hours or 25 minutes.

Explanation:

That is 1/6 of 2 1/2 hours.

2 1/2 = 5/2.

6/2 * 1/6 = 5/12 hours or 5/12 * 60 = 25 minutes.

Answer 2

25 minutes

Explanation:

Two and a half hours is (60 + 60 + 30) minutes, i.e. 150 min.

If a reading time is one sixth of the 150 minutes, it means that the reading time is:

150*(1/6) = 150/6 = 25

Therefore, 25 minutes of the exam is a reading time.
