Answer:
Tommy has 12 slices
Step-by-step explanation:
1. You have 4 cakes, and it says to cut it into thirds.
2. So, each cake gets cut into three pieces.
3a. Now you have 12 pieces (or slices!) of cake.
3b. From cutting the cakes into three pieces, you could also just multiply the 4 cakes by 3 (the number of slices), and you would get 12, the answer.
