Final answer:
The pot can hold 3 2/3 more quarts of water.
Step-by-step explanation:
To find out how many more quarts of water the pot can hold, we need to subtract the amount of water already in the pot from the total capacity of the pot. The pot has a capacity of 5 1/2 quarts, and it is filled 2/3 of the way, which is equal to (2/3) * (5 1/2) = 11/6 quarts. To find how many more quarts can fit in the pot, we subtract the amount of water already in the pot from its total capacity: 5 1/2 - 11/6 = (33/6) - (11/6) = 22/6 = 3 2/3 quarts.
