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 think it is this because sally has 2/3 of a cake and robert eats 1/3 which means he took one away.
