Give the step-by-step reasoning process and then the final answer. Maria is chopping up vegetables for a stew. She wants to cut up six times as many carrots as potatoes, twice as many onions as carrots, and 1/3 as many green beans as onions. If she has two potatoes, how many green beans does she need to cut?
First find how many carrots Maria needs to cut by multiplying the number of potatoes by 6: 6 * 2 = 12. Then find how many onions she needs by multiplying the number of carrots by 2: 12 * 2 = 24. Finally, divide the number of onions by 3 to find the number of green beans she needs 24 / 3 = 8.
The final answer: 8.
