One way to find the answer to this question would be to use a bar model. Draw a long rectangle and label it, "12". Then, cut the bar into 3 pieces. Color in one of the boxes. This represents the one-third of peanut butter cookies. Since you split 12 into 3 pieces, divide 12 by 3. You'll get the answer 4. That means out of the 12 pack of cookies, 4 of them are peanut butter. Hope I helped you. :)
