hours = floor(decimal) · minutes = (decimal − hours) × 60
For 7.75 in hours and minutes: the whole number is 7 hours, and 0.75 × 60 = 45 minutes, so the answer is 7 hours 45 minutes. The calculator above shows this the instant you type.

When to Convert Decimal Hours to Time
You usually convert decimal hours to time when reading a system total back to a human. A timesheet might say 38.25 hours this week — that is 38 hours 15 minutes. Billable-hours reports, payroll summaries and project trackers all store decimal hours, so flipping them back to hours and minutes helps you sanity-check the number before sending an invoice or a pay run.
