110/1 is a longshot implying 0.90%. Long fractional prices move in big steps (16/1, 20/1, 25/1, 33/1), and bookmakers shade them heavily, so the fair price is usually longer than the quoted one suggests.
Converting 110/1 by hand
Divide the top of the fraction by the bottom and add one for the decimal price, 111.00. For the implied probability, divide the bottom by the sum of top and bottom: 0.90%. American odds follow from the decimal price: odds-against, so (111.00 − 1) × 100 gives +11,000. The same chance on a prediction market is a 1¢ share.
The vig at 110/1
