How this conversion works
Keep the 1 whole hour. Convert the minutes on their own: 45 ÷ 60 = 0.75. Add that fraction to the hours: 1 + 0.75 = 1.75.
Write 1.75 on the timesheet. Do not write 1.45. Putting the minutes after the dot is the usual mix-up, and it short-changes the time. 45 minutes is 0.75 of an hour, so 1 hour 45 minutes is 1.75, not 1.45.
