When the new Diary of a Wimpy Kid book came out, Jack's mom bought 42 bags of cheese-doodles for a celebration at the bookstore. The customers only ended up eating 3 bags, so Jack's mom gave Jack the rest of the cheese-doodles to eat!
Jack decided that he would eat 2 bags on Monday, 4 bags on Tuesday, and 7 bags on Wednesday. Jack had a stomach ache on Thursday, so he decided he wouldn't eat anymore, and counted his remaining bags instead. How many bags did he have left? Give your answer as a fraction of Jack's original 39 bags, in LOWEST TERMS.
