I'm supposed to calculate hours worked on a timecard and round down to the nearest quarter hour, as in "7 1/4" or "7 1/2". I'm having trouble with the rounding, and where I'm supposed to round down or up with this.

One of the questions is for Friday: In- 7:05: Out- 11:10: In- 11:40: Out-2:50.

What were the total hours?
