18 is the answer.
If you keep having problems solving problems like this you can simply draw (in this example) 6 circles and tear each of them in three pieces, there are your thirds!
Then just count them and it's done.
3 thirds are in one whole
6, each whole is 3 thirds
You can only get one 2/3 out of a whole, since two times two thirds is four thirds which is one and a third, hence, larger than a whole.

I believe that there are three thirds in nine.
3 thirds are in one whole
6, each whole is 3 thirds
There are 6 because 6/3 = 2
6 Thirds are in 2 wholes. 3 in 1 whole.
You can only get one 2/3 out of a whole, since two times two thirds is four thirds which is one and a third, hence, larger than a whole.
There are 0.06 of them.
Four ones divided by ten thirds = 6/35 (six thirty-fifths).

6 2/3 / 1/3 = 20
There is 9 two thirds In 6 cups!
