I think that this is the answer because sally onlyy has 2 and robert ate 1/3 of 2/3 and of means x so that means that you have to multiply.

It's like that because the sentence says that Robert ate 1/3 of this piece (2/3). Since 'of' means multiply, you need to do 1/3 x 2/3 which is 2 1/3, which robert ATE 1/3 OF 2 / 3 which was what the sentences said.
