## Subtract Days and Hours

### Subtract Days and Hours: Learn

How to subtract days and hours:

• If the number of hours being subtracted is larger than the original hours, you must borrow some hours from the days:
• Subtract 1 from the original number of days.
• Increase the number of original hours by 24.
• Subtract the hours.
• Subtract the days.

Example: What is 4 days 1 hour minus 2 days 6 hours?

• Since 6 hours is more than 1 hour, we must borrow some hours:
• Subtract 1 from the original days: 4 days - 1 day = 3 days
• Add 24 to the original hours: 1 hour + 24 hours = 25 hours
• Subtract the hours: 25 hours - 6 hours = 19 hours
• Subtact the days: 3 days - 2 days = 1 day
• Final answer: 1 day 19 hours
