if 1.5 hens can lay 1.5 eggs in 1.5 days, how many eggs can 7 hens lay in 6 days?
***
It takes 1.5*1.5=2.25 hen-days to lay 1.5 eggs
7 hens laying eggs for 6 days=7*6=42 hen-days
(42/2.25)*1.5=28
how many eggs can 7 hens lay in 6 days? 28

1.5 hens can lay 1.5 eggs in 1.5 days
--------------------------------------
Twice as many hens will lay twice as many
eggs in the same amount of time, so
--------------------------------------
3 hens can lay 3 eggs in 1.5 days
--------------------------------------
1/3 as many hens can lay 1/3 as many eggs
in the same amount of time
--------------------------------------
1 hen can lay 1 egg in 1.5 days
--------------------------------------
by the same reasoning,
7 hens can lay 7 eggs in 1.5 days
--------------------------------------
The same number of hens can lay 4 times
as many eggs in 4 times as many days, so
--------------------------------------
7 hens can lay 28 eggs in 6 days
