Give the step-by-step reasoning process and then the final answer. James and Lisa ordered 2 small pizzas. Each pizza has 6 slices. James ate 2/3 of all the slices. How many slices of pizza did James eat?
There are a total of 2 * 6 = 12 slices of pizza. Since James ate 2 / 3 of all the slices, he ate 2 / 3 * 12 = 8 slices of pizza.
The final answer: 8.
