Correct Option: A

AI Explanation

To find the ratio of 12 minutes to one hour, we need to convert both values to the same unit of time.

There are 60 minutes in one hour.

So, if we divide one hour (60 minutes) by 12 minutes, we get:

60 minutes / 12 minutes = 5

This means that 12 minutes is 1/5th of one hour.

Therefore, the ratio of 12 minutes to one hour is 1:5.

So, the correct answer is option A) 1:5.
