<human>:  Bill is stocking the kitchenware section of the Walmart. He needs to stack 60 pots. On each shelf, he can stack five pots vertically and three sets of vertically stacked pots side-by-side. How many shelves does he need to stock all the pots?
<bot>: How many pots fit on one shelf? ** First find how many pots fit on one shelf: 5 pots/set * 3 sets = <<5*3=15>>15 pots
How many shelves does Bill need to stock all the pots? ** Then divide the number of pots Bill has by the number that fit on each shelf: 60 pots / 15 pots/shelf = <<60/15=4>>4 shelves
