What 11/2 means
With fractional odds, the first number is what you win and the second is what you stake. At 11/2, every £2 you stake wins £11 in profit, and your stake is returned on top. Because you win more than you stake, it's an odds-against price: the bookmaker rates this outcome as less likely to happen than not.
It's read as "eleven to two".

How likely is 11/2 to win?
11/2 implies a 15.4% chance, or about 2 in 13. In other words, the bookmaker expects it to win roughly two times for every thirteen attempts. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
11/2 each way
An each way bet splits your stake between a win bet and a place bet, with the place part paid at a fraction of 11/2. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 11/8 | £44.38 | £11.88 |
| 1/5 odds | 11/10 | £43.00 | £10.50 |
At 1/5 terms, a placed finish alone returns £10.50 from the £10 total stake, so the place part covers the whole bet with £0.50 to spare. Work out any each way bet.
If a horse at 11/2 is withdrawn
When a horse priced at 11/2 is withdrawn after you've bet on another runner in the same race, Rule 4 takes 15p from every £1 of your winnings. It applies to bets struck at a fixed price before the withdrawal. Work out a Rule 4 deduction.
