Here we will show you two different methods to convert and write 3 hours and 21 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 3 hours to minutes by multiplying it by 60.
Then we add that number to the 21 minutes and divide the total by 60. Here is the math and the answer:
(3 x 60) + 21 = 201 minutes
201 / 60 = 3.350 hours
Method 2:
You could also make the minutes into a fraction as 21/60, which is the same as 21 divided by 60. Then you
add that result to the 3 hours. Here is the math to illustrate:
21/60 = 0.350
3 + 0.350 = 3.350 hours
Note: Answers on this page are rounded to the nearest three decimals.
