a 4 minute egg is cooked for what fraction of an hour?
is it 1/15
Right.
To determine the fraction of an hour, we need to convert the given time into minutes, then express it as a fraction of 60 minutes (which is equivalent to an hour).
Since there are 60 minutes in an hour, we need to find the fraction of 60 minutes that corresponds to 4 minutes. To do this, we divide the number of minutes (4) by the total number of minutes in an hour (60):
4 minutes รท 60 minutes = 1/15
So the correct answer is indeed 1/15. A 4-minute egg is cooked for 1/15 of an hour.
