To me: given that the juice is sugar free means that I can ignore the 3 sugar apple juices and the 10 sugr grape juices.
Therefore the field of drinks is 14 sugar free drinks and the changes that it is apple juice, is 9:14 or 9/14.
If, on the other hand, the problem is saying that the juice must be sugar free and also apple, that would be 9/27 or 1/3
