7h 45m = 7.75 hours

Common payroll mistake: 8h 30m is 8.50 hours, not 8.30. Minutes are 1/60 of an hour, not 1/100 — 30 minutes = 0.50.

Payroll convention: two decimals. Values marked * are rounded (minutes ÷ 60). FLSA time-rounding note: when rounding punches to the quarter hour, 1–7 minutes round down and 8–14 round up (the "7-minute rule"). For reference only — not legal or payroll advice.
