If each time is rounded to the nearest tenth which student would have a time of 12.7?

Colin

Explanation:

To rounds to the nearest tenth you look at the number after (in the hundredth's place) if it's below 5 you round down, if it's 5 or more you round up.

12.77 rounds to 12.8 because 7 is more than 5 so it rounds up.

12.63 rounds to 12.6 because 3 is less than 5 so it rounds down.

12.75 rounds to 12.8 because 5 is equal to 5 so it rounds up.

12.68 rounds to 12.7 because 8 is more than 5 so it rounds up.
