Working together adds the rates
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 = 5/…
6 days
Combined they do 5 units each day, so 30 ÷ 5 = 6.
💡 The LCM trick kills all fractions — that's its whole point.
