Ateapot is 1/3 full of tea. when all of the tea is poured into an empty container, the container ie 2/3 full. what fraction of the tea from a full teapot is needed to fill 1 entire container?

So.. we took 1/3 that was in the teapot, dumped it into the container, and the container ended up 2/3 of the way, now, to fill the container, all we need is really 1/3, because 2/3 + 1/3 is 3/3 or 1 whole

so.. how much is 1/3 of the container, in teapot's terms?

well     

The second and fourth answer are correct
