Here we will show you two different methods to convert and write 28 hours and 80 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 28 hours to minutes by multiplying it by 60.
Then we add that number to the 80 minutes and divide the total by 60. Here is the math and the answer:
(28 x 60) + 80 = 1760 minutes
1760 / 60 = 29.333 hours
Method 2:
You could also make the minutes into a fraction as 80/60, which is the same as 80 divided by 60. Then you
add that result to the 28 hours. Here is the math to illustrate:
80/60 = 1.333
28 + 1.333 = 29.333 hours
Note: Answers on this page are rounded to the nearest three decimals.
