Answer 2

[AI-generated answer — Step-by-Step Bot]

To find out what fraction of the TV programme is left, we need to subtract the time elapsed from the total duration of the programme.

a) After 10 minutes:
Total duration - Time elapsed = 40 minutes - 10 minutes = 30 minutes

So, there are 30 minutes left. The fraction can be written as 30/40, which simplifies to 3/4.

b) After 15 minutes:
Total duration - Time elapsed = 40 minutes - 15 minutes = 25 minutes

So, there are 25 minutes left. The fraction can be written as 25/40, which can be simplified to 5/8.

c) After 35 minutes:
Total duration - Time elapsed = 40 minutes - 35 minutes = 5 minutes

So, there are 5 minutes left. The fraction can be written as 5/40, which can be simplified to 1/8.
