Here we will show you two different methods to convert and write 7 hours and 9 minutes as a decimal.
Method 1:
Because there are 60 minutes in an hour (not 100), we can first convert the 7 hours to minutes by multiplying it by 60.
Then we add that number to the 9 minutes and divide the total by 60. Here is the math and the answer:
(7 x 60) + 9 = 429 minutes
429 / 60 = 7.150 hours
Method 2:
You could also make the minutes into a fraction as 9/60, which is the same as 9 divided by 60. Then you
add that result to the 7 hours. Here is the math to illustrate:
9/60 = 0.150
7 + 0.150 = 7.150 hours
Note: Answers on this page are rounded to the nearest three decimals.
