The first number is the size of each ply that makes up the yarn. The second number is how many plies the yarn has. So 3/2 is two plies of size three yarn and 5/2 is two plies of size five yarn. The number that describes the size is larger the thinner the yarn. So size 5 yarn is thinner than size 3 yarn.
