(1) I am really sorry but I don't know how to answer this one.
(2)The answer for question 2 is 3qt/69oz. This is because to get it in its simplest form you must divide 6 by 2 and 138 by 2. You can make it even simpler because you can dived 6 by 3 and 138 by 3 and get 2qt/ 46oz and then it can get even smaller because you can divide 2 by 2 and get 1 adn 46 by 2 and get 1qt/23oz.
I hope this helped you!
