Here we will show you two different methods to convert and write 40 hours and 91 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 40 hours to minutes by multiplying it by 60.
Then we add that number to the 91 minutes and divide the total by 60. Here is the math and the answer:
(40 x 60) + 91 = 2491 minutes
2491 / 60 = 41.517 hours
Method 2:
You could also make the minutes into a fraction as 91/60, which is the same as 91 divided by 60. Then you
add that result to the 40 hours. Here is the math to illustrate:
91/60 = 1.517
40 + 1.517 = 41.517 hours
