If you had w cookies and each bag has x cookies How many bags of cookies do you have?
There are w = 33 cookies in total. 
Each bag has x = 11 cookies. 
Therefore, the number of bags of cookies is equal to w / x = 33 / 11 = 3. 

In other words, if you have w cookies and each bag has x cookies, you have w / x bags of cookies.
