How this conversion works
Keep the 8 whole hours. Convert the minutes on their own: 15 ÷ 60 = 0.25. Add that fraction to the hours: 8 + 0.25 = 8.25.
Write 8.25 on the timesheet. Do not write 8.15. Putting the minutes after the dot is the usual mix-up, and it short-changes the time. 15 minutes is 0.25 of an hour, so 8 hours 15 minutes is 8.25, not 8.15.
