Final answer:
To record 8 hours and 15 minutes on a time card, write '8:15' for clock-in/out systems, '8 hours and 15 minutes' if fully written, or '8.25 hours' for decimal systems.
Step-by-step explanation:
To write 8 hours and 15 minutes on your time card, simply write out the hours followed by the minutes. In many time cards or digital systems, you will format this as either '8:15' for a clock-in/clock-out system, or write '8 hours and 15 minutes' if it requires spelling out the duration. If the time card operates on a decimal system, which some employers use, then you would convert the 15 minutes to a decimal by dividing 15 by 60 to get 0.25. In this case, you would write '8.25 hours' on your time card.
