One and a Half Hens Puzzle - Solution

The Puzzle:

If one and a half hens lay one and a half eggs in one and a half days, how many eggs does one hen lay in one day?

Our Solution:

Find the daily rate per hen:

Hens × Days × (Daily Rate) = Eggs

1½ × 1½ × (Daily Rate) = 1½

(Daily Rate) = 1½ / (1½ × 1½)

Daily Rate = 1/(1½) = 2/3

So 1 hen in 1 day will lay two-thirds of an egg
