Here we will show you two different methods to convert and write 9 hours and 39 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 9 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:
(9 x 60) + 39 = 579 minutes
579 / 60 = 9.650 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 9 hours. Here is the math to illustrate:
39/60 = 0.650
9 + 0.650 = 9.650 hours
Note: Answers on this page are rounded to the nearest three decimals.
