<human>:  A three-toed sloth moves very slowly, and only eats when he is up in his tree. For a meal of berries, it takes the sloth 4 hours to make the trip down the tree, pick up berries, and climb back up into his tree. Assuming he picks the same number of berries on each trip, what is the least number of berries he can pick up per trip down to the ground if he wants to collect 24 berries in 8 hours?
<bot>: How many trips can he make in 8 hours? ** If one trip is 4-hours long, in 8 hours he can make 8/4=<<8/4=2>>2 trips.
How many berries does he need to collect per trip? ** To collect 24 berries per 2 trips, he needs to collect 24 / 2 = <<24/2=12>>12 berries per trip.
