Here we will show you two different methods to convert and write 38 hours and 39 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 38 hours to minutes by multiplying it by 60.
Then we add that number to the 39 minutes and divide the total by 60. Here is the math and the answer:
(38 x 60) + 39 = 2319 minutes
2319 / 60 = 38.650 hours
Method 2:
You could also make the minutes into a fraction as 39/60, which is the same as 39 divided by 60. Then you
add that result to the 38 hours. Here is the math to illustrate:
39/60 = 0.650
38 + 0.650 = 38.650 hours
