There are 60 seconds in a min. and 60 mins. in an hour = 3600 seconds in an hour. 19 seconds is therefore 19/3600 of and hour.
It is: 60 seconds = 1 minute which is 1/60 of an hour
1/5 of an hour.
1 hour = 60 minutes = 60*60 seconds = 3600 seconds So 20 seconds, as a fraction of an hour = 20/3600 = 1/180
The fraction of 8 seconds/ 1 hour = 8 seconds/ 60 minutes = 8 seconds/ 3600 seconds. This would mean that 8 seconds is 1/ 450 of a hour and that 8 seconds is 0.222% of a hour.
There are 60 minutes in one hour. Therefore, 39 minutes is equal to 39/60 or 13/20 hours, or thirteen twentieths of an hour.
