To find A∩B (the intersection of A and B), we need to determine the elements that are present in both A and B.
Looking at the sets A and B, we can see that 3 and 4 are present in both sets. Additionally, ⅓ is also present in both sets.
Therefore, the intersection of A and B is {3, 4, ⅓}.
Hence, option C: {3, 4, ⅓} is the correct answer.
