Here we will show you two different methods to convert and write 6 hours and 87 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 6 hours to minutes by multiplying it by 60.
Then we add that number to the 87 minutes and divide the total by 60. Here is the math and the answer:
(6 x 60) + 87 = 447 minutes
447 / 60 = 7.450 hours
Method 2:
You could also make the minutes into a fraction as 87/60, which is the same as 87 divided by 60. Then you
add that result to the 6 hours. Here is the math to illustrate:
87/60 = 1.450
6 + 1.450 = 7.450 hours
Note: Answers on this page are rounded to the nearest three decimals.
