Answer:
16
Step-by-step explanation:
well 1 dozen equals 12 since she has 2 dozens it means she has 24 cookies in total for now. Then you would have to divided by 3. So 24 divided by 3 you will get 8. So 8 cookies per 1/3 but as it says in the problem it was 2/3 which means you duplicate the 8 so it would be 8*2 which is 16 so she has 16 cookies that were oatmeal.
