When this gets tricky
Do not write 9.45; that means 9.45 decimal hours, not 9 hours 45 minutes.
If lunch is unpaid, subtract lunch after converting the full shift span.
If overtime applies, confirm whether 9.75 is a daily total or part of a weekly total.

9 hours 45 minutes → 45 ÷ 60 = 0.75 → 9 + 0.75 = 9.75 decimal hours.
Keep the inputs visible. That makes the answer easier to reuse in a timesheet note, payroll message, PTO request, or deadline explanation.
