Sally has \( \frac{2}{3} \) of a whole cake in the fridge. Robert eats \( \frac{1}{3} \) of this piece. What fraction of the whole cake has Robert eaten? Choose the number sentence that would solve the word problem.
\( \frac{2}{3}-\frac{1}{3} \)
i know this is the answer because you need to get to 1/3 and by taking 1/3 away from 2/3 you get 1/3.
