<human>:  If Jason eats three potatoes in 20 minutes, how long, in hours, would it take for him to eat all 27 potatoes cooked by his wife?
<bot>: How many minutes are in 20 minutes? ** Since 1 hour is 60 minutes, 20 minutes is 20/60=1/3 of an hour.
How many potatoes does Jason eat in an hour? ** Eating 3 potatoes per 20 minutes is 3/(1/3)=<<3/(1/3)=9>>9 potatoes per hour.
How many hours will it take Jason to eat all of the potatoes? ** At 9 potatoes per hour, it will take Jason 27/9=3 hours to eat all of the potatoes.
