Okay, in the problem we know that Molly jump rope is 6 1/3 feet long and that Gails jump rope is 4 2/3 feet long, we want to know how much longer is Molly jump rope than of Gails, in this problem we have to subtract 6 1/3 - 4 2/3, once we subtract them the answer is 1 2/3, so Molly jump rope is 1 2/3 longer than Gails jump rope.
