It's a computation. It would be 8!/3!(8-3)! If my memory serves me correctly.
Answer:
4 eggs per hen
Step-by-step explanation:
You would need to divide the total number of eggs by the number of hens to see how many each one would produce:
Thus, 64/16 = 4
That gets you 4 eggs per hen!
675 : 5 = 135
135 : 5 = 27
27 : 3 = 9
9 : 3 = 3
3 : 3 = 1
675 = 5 · 5 · 3 · 3 · 3 = 5² · 3³
