A chicken and a half lay an egg and a half in a day and a half. How many eggs would one chicken lay in three days?

Help: 3 is not the correct answer.

    Additional help: It is like when you calculate things related to different units. You should define the units first to give meaning to relationship between numbers.

    Last time I checked 1 + 1 = 2

      Bravo! You are smart Karen.
      The way I would solve it is this, not as brilliant as yours though:
      1.5 (chiken) * 1.5 (day) = 1.5 (egg) * k (chiken.day per egg)
      So it is easy enough to find out the k. k = 1.5 which means each egg takes 1.5 (or 3/2) chiken.days
      From that is easy to calculate the answer which is 3 * (1/1.5) = 2

      Non mathematical way is to say, well a chicken and half lays three eggs in three days, so a chicken lays two eggs in three days.
