How to convert decimal hours to hours and minutes
- The whole number is the hours: in 7.75, that's 7 hours.
- Multiply the decimal part by 60 to get minutes: 0.75 × 60 = 45 minutes.
- If there is still a decimal, multiply it by 60 again for seconds.
So 7.75 hours = 7 hours 45 minutes, and 3.2 hours = 3 hours 12 minutes (0.2 × 60 = 12).
