Convert decimal hours to hours and minutes
To convert decimal hours back into hours and minutes, keep the whole-number portion as the hours and multiply the decimal portion by 60.
Whole hours = 7 0.75 × 60 = 45 minutes 7.75 hours = 7 hours 45 minutes The reverse conversion rounds the minute portion to the nearest whole minute. If rounding produces 60 minutes, the result rolls over to the next full hour.
