Pipes fill; outlets drain

Call the whole job LCM(times) units so each rate is a whole number. Add the per-day units, then divide the job by the combined rate.

A
3 units/unit-time
B
2 units/unit-time
job = 30 units; rate = 3 2 = 1/…
30 hours
Combined they do 1 units each hour, so 30 ÷ 1 = 30.

💡 The LCM trick kills all fractions — that's its whole point.
