Final answer:
To convert minutes to hours and minutes, divide the total number of minutes by 60 to get hours and the remainder as minutes.
Step-by-step explanation:
a) 180 minutes is equal to 3 hours. Since there are 60 minutes in an hour, dividing 180 by 60 gives us 3 hours.
b) 204 minutes is equal to 3 hours and 24 minutes. Dividing 204 by 60, we get 3 as the whole number of hours and the remainder of 24 as the minutes.
c) 210 minutes is equal to 3 hours and 30 minutes. In the same way, dividing 210 by 60 gives us 3 hours and the remainder of 30 as the minutes.
