Question 1028470
What does 1/3 mean? It means 1 out of 3, so the whole is made up of three identical pieces. 
So if we have a pizza and cut it in three equal pieces, see picture and then you tell me how much is left for the third person. And you know how to use your calculator, right? So you can divide 3300/3 and then put the answer you get on each of the slices?
