Mauricio wants to fry 18 potatoes per hour for 3.5, point, 5 hours. He can fry 6 potatoes using each gallon of oil. How many gallons of oil does Mauricio need for frying potatoes?
honestly I couldn't understand most of that but if one gallon of oil is needed to fry 6 potatoes, and he wants to fry 18 potatoes, then he'll end up using 3 gallons
