How to convert
Divide the minutes by 60 and add them to the hours. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. To go back, multiply the part after the decimal point by 60: 0.75 × 60 = 45 minutes.
Be careful not to read 7.30 as 7 hours 30 minutes. In decimal hours, 7.30 is 7 hours 18 minutes, and 7 hours 30 minutes is 7.5.
