Part a: x/10 represents the amount of pills given divided by the amount of mg's in each pill. 
Part b: 9*x/10 represents the number of pills given in each day of the nine days  and how many mg' are in the total dosage for the nine days. 
Part c: If Jack has to give his dog 30 pills in nine days the entire expression represents the number of pills given to the dog each day and how many mg's of medicine the dog is consuming.
