'Commutative' means you can work it in the other direction without changing it.
But 1/2 is not the same number as 2/1 . So I guess division is NOT commutative.
Answer:
Let total number of dog and cat population in animal shelter be x.
As per the statement:
An animal shelter has 9 puppies.
⇒ Total number of puppies = 9
It is also given that if the puppies are 36% of the total dog and cat population.
⇒ 
or

By cross multiply we get;

Divide both sides by 36 we get;

Therefore, total number of dogs and cat population in animal shelter are 25
I beleive 144=2 is the answer.
If you have to divide that to get 1 number it would be 72.
