The volume of pitcher I is A ounces, and the volume of pitcher II is B ounces, with B > A. If pitcher II is full of water and pitcher I is empty, and if just enough water is poured from pitcher II to fill pitcher I, what fraction of pitcher II is now full?
(A)\(\frac { 1 } { 2 } \) (B)\(\frac { 1 } { B } \) (C)\(\frac { A } { B } \) (D)\(\frac { A - B } { B } \) (E)\(\frac { B - A } { B } \)
E
