Answer:
B
Explanation:
Funny, because i'm learning about this right now. The best way to solve this is to imagine it in real life. Imagine having 2/3 of a cup of sugar to make 1/4 of a cake. To make a whole cake, you would need to multiply 1/4 times 4, to get 1 sheet cake. You have to do the same thing with the cups of sugar: 2/3 times 4, which would get you 2 2/3 cups, which is B. Please correct me if I am wrong, everybody makes mistakes.
