Chris has half as many cookies as Kenny. Glenn has four times as many cookies as Kenny. How many cookies do these three boys have, if Glenn has 24 cookies? Let's be accurate as possible.
Kenny has 24 / 4 = 6 cookies. Chris has 6 / 2 = 3 cookies. These three boys have 24 + 6 + 3 = 33 cookies.
The answer: 33.
