Here we will show you two different methods to convert and write 39 hours and 72 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 39 hours to minutes by multiplying it by 60.
Then we add that number to the 72 minutes and divide the total by 60. Here is the math and the answer:
(39 x 60) + 72 = 2412 minutes
2412 / 60 = 40.200 hours
Method 2:
You could also make the minutes into a fraction as 72/60, which is the same as 72 divided by 60. Then you
add that result to the 39 hours. Here is the math to illustrate:
72/60 = 1.200
39 + 1.200 = 40.200 hours
