Here we will show you two different methods to convert and write 66 hours and 31 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 66 hours to minutes by multiplying it by 60.
Then we add that number to the 31 minutes and divide the total by 60. Here is the math and the answer:
(66 x 60) + 31 = 3991 minutes
3991 / 60 = 66.517 hours
Method 2:
You could also make the minutes into a fraction as 31/60, which is the same as 31 divided by 60. Then you
add that result to the 66 hours. Here is the math to illustrate:
31/60 = 0.517
66 + 0.517 = 66.517 hours
