You can put this solution on YOUR website! if four hens lay 9 eggs in 7 days, how many days will it take four dozen hens to lay 27 dozen eggs?
------
# of days is directly lated to # of eggs and indirectly related to # of hens.
----
d = k*e/h
--------------
Solve for "k" using "four hens lay 9 eggs in 7 days"
7 = k*9/4
k = 28/9
---
Equation:
d = (28/9)e/h
-------
Solve "how many days will it take four dozen hens to lay 27 dozen eggs?".
---
d = (28/9)27/48
---
d = (7/12)*3
---
# of days = 7/4 = 1 3/4
