A chicken farmer has figured out that a hen and a half can lay an egg and a half in a day and a half. How many hens does the farmer need to produce one dozen eggs in six days?
1.5 hen 1.5 days = 1.5 eggs 3 hens 1.5 days = 3 eggs 3 hens 6 days (1.5 * 4) = 12 eggs
Need 3 hens to have 12 eggs in 6 days
1.5 hens/1.5 days=1 hen/day (1 hen/day)/1.5 eggs=2/3 eggs per day per hen 12 eggs/6 days=2 eggs/day (2 eggs/day)/(2/3 eggs per hen per day)=3 hens necessary ☺☺☺☺
Half hen is impossible
