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.
\( \frac{2}{3}-\frac{1}{3} \)
2/3 - 1/3 = 1/3 this is because he eats the cake which means you take it away.
