Here we will show you two different methods to convert and write 39 hours and 51 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 51 minutes and divide the total by 60. Here is the math and the answer:
(39 x 60) + 51 = 2391 minutes
2391 / 60 = 39.850 hours
Method 2:
You could also make the minutes into a fraction as 51/60, which is the same as 51 divided by 60. Then you
add that result to the 39 hours. Here is the math to illustrate:
51/60 = 0.850
39 + 0.850 = 39.850 hours
