Counting Chickens

If one-and-a-half chickens lay one-and-a-half eggs in one-and-a-half days, how many eggs does one chicken lay in one day? Click below for the answer.

For many people, the intuitive answer is one egg, but it pays double-check your math on this kind of problem. The daily rate of eggs per chicken per day is given by the formula

daily rate = eggs / (chickens x days)

Plugging in the numbers from the first part of the problem, we get

daily rate = 1.5 / (1.5 x 1.5)
daily rate = 1.5 / 2.25
daily rate = 2/3

So, one chicken lays two-thirds of an egg in one day.
