You have to know that 1 day = 24 hours and 1 hour = 60 minutes. The tricky part is converting hours:minutes into decimal hours. 15 minutes = 15/60 = 1/4 = 0.25 hours Therefore 7 hrs 15 min = 7.25 hours What fraction of a day? 7.25 / 24 = .30208333... = 30.2 percent
It is: 24 hours minus 8 hours 15 minutes = 15 hours 45 minutes
There are 60 minutes in an hour, thus: 924/60 gives you the number of hours = 15 hours (15.4 actually but you only take the whole part) and 15*60 is the number of minutes in 15 hours = 900 minutes. thus 924-900= 24 Therefore there are 15 hours and 24 minutes in 924 minutes.
