A glass of water that is 9/10 full has less water then a pool that is 5/10 full. A swimming pool (if you think about it) has way more water then one glass of water. Even though the number for the glass is higher it has less water becuase the glass is smaller. The pool on the other hand can vary in sizes but it'll always be bigger then a small glass. The for a glass of water that is 9/10 of a way full has less water making that the answer
