There could be two unit rates for this problem. We find the unit rate by dividing how much something gets for however much it is. For example:
If we wanted to find out how many pounds of dog food each dog gets, we divide the pounds of dog food all of them get by how many dogs there are:
128/16 = 8
So each dog receives 8 pounds of dog food. This is one unit rate.
Another unit rate would be how many dogs does one pound of dog food feed. We calculate this by dividing the amount of dogs by the pounds of dog food they received:
16/128 = 1/8
So one pound of dog food feeds 1/8 of a dog, this is the other unit rate.
