How it works
An hour has 60 minutes, so dividing minutes by 60 gives hours. The answer can be written two ways: as decimal hours, which payroll and invoicing systems use (90 minutes = 1.5 hours), or as hours and minutes, which is how we usually say a duration (1 hour 30 minutes). Be careful not to mix the two — 1.5 hours is 1 hour 30 minutes, not 1 hour 50 minutes.
