Ann, Bill, Cate, and Dale each buy personal pan pizzas cut into 4 pieces. If Bill and Dale eat 50% of their pizzas and Ann and Cate eat 75% of the pizzas, how many pizza pieces are left uneaten? Let's think first. Chain of thought:
User
In total, there are 4 x 4 = 16 pizza pieces. Bill and Dale eat 2 x 4 x 50% = 4 pieces. Ann and Cate eat 2 x 4 x 75% = 6 pieces. The four of them eat 4 + 6 = 10 pieces. There are 16 - 10 = 6 pizza pieces uneaten.
Therefore, the answer is 6.
