Here we will show you two different methods to convert and write 68 hours and 21 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 68 hours to minutes by multiplying it by 60.
Then we add that number to the 21 minutes and divide the total by 60. Here is the math and the answer:
(68 x 60) + 21 = 4101 minutes
4101 / 60 = 68.350 hours
Method 2:
You could also make the minutes into a fraction as 21/60, which is the same as 21 divided by 60. Then you
add that result to the 68 hours. Here is the math to illustrate:
21/60 = 0.350
68 + 0.350 = 68.350 hours
Note: Answers on this page are rounded to the nearest three decimals.
