For every 12 monkeys that a zoo keeps, it must hire 3 zookeepers. If a zoo is rehabilitating 228 monkeys, how many zookeepers does the zoo need

Answer 1

If a zoo keeps 12 monkeys, it hires 3 zookeepers, so for 228 monkeys, the zoo would need 228/12 = <<228/12=19>>19 sets of 12 monkeys.
19 sets of 12 monkeys need 19*3 = <<19*3=57>>57 zookeepers. Answer: \boxed{57}.
