Here we will show you two different methods to convert and write 28 hours and 77 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 77 minutes and divide the total by 60. Here is the math and the answer:
(28 x 60) + 77 = 1757 minutes
1757 / 60 = 29.283 hours
Method 2:
You could also make the minutes into a fraction as 77/60, which is the same as 77 divided by 60. Then you
add that result to the 28 hours. Here is the math to illustrate:
77/60 = 1.283
28 + 1.283 = 29.283 hours
Note: Answers on this page are rounded to the nearest three decimals.
