Each cow has two ears and four feet. Multiply 2 by 16, and we get 32 cow ears. Multiply 16 by 4 and we get 64 feet. Then you make a part to part ratio, using the ear count and feet count.
It is 32:64 because if you do 2 ears multiplied by 16 cows it will equal to 32, and when you do 4 cow feet multiplied by 16 cows you will get 64. Hope This Helps!
