It is: 45/60 which is 3/4 of an hour in its simplest form
It is: 20/(60*60) = 1/180 of an hour
To calculate 45 seconds as a fraction of 1 hour, first convert 1 hour to seconds. Since 1 minute is 60 seconds, 1 hour is equal to 60 minutes x 60 seconds = 3600 seconds. Next, divide 45 seconds by 3600 seconds to find the fraction of 1 hour. This results in 45/3600 = 1/80 of an hour, or 0.0125 hours.
It is: 60 seconds = 1 minute which is 1/60 of an hour
1/5 of an hour.
1 hour = 100% 1 minute in an hour = 1/60 therefore 30 seconds in an hour = 1/120
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.
