Here we will show you two different methods to convert and write 3 hours and 12 minutes as a decimal.|
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 12 minutes and divide the total by 60. Here is the math and the answer:
(3 x 60) + 12 = 192 minutes
192 / 60 = 3.200 hours
You could also make the minutes into a fraction as 12/60, which is the same as 12 divided by 60. Then you
add that result to the 3 hours. Here is the math to illustrate:
12/60 = 0.200
3 + 0.200 = 3.200 hours
