How do we draw it exactly
-1/3=-3-/9
-4/9-3/9=-7/9
z-7/9=5/9
7/9+5/9=12/9
z=1 1/3
The answer is 6 eggs per hen. You divide 72 by 12 to get 6. Hope it helps.
You basically determine your answer by doing 62-47 and then you take difference of that, which is 15 and you have the difference in the cubs weight.
