Answer:
3
Step-by-step explanation:
Mean= add up all the numbers, then divide by how many numbers there are. 0+3+6=9
9/3=3
So the way I would do this is by finding 72 heads with them all being chickens. So basically multiply 72 by 2 to get 144 legs. So this means that 56 more legs are needed. And since the difference between legs of chickens and rabbits is two, then we just divide 56 by two to figure out how many rabbits there are.
56/2 = 28
And then to figure out the number of chickens, just do 72 - 28 = 44.
So there are 28 rabbits, and 44 chickens.
