What 9/1 means
With fractional odds, the first number is what you win and the second is what you stake. At 9/1, every £1 you stake wins £9 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 "nine to one".

How likely is 9/1 to win?
9/1 implies a 10.0% chance, or about 1 in 10. In other words, the bookmaker expects it to win roughly once for every ten attempts. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
9/1 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 9/1. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 9/4 | £66.25 | £16.25 |
| 1/5 odds | 9/5 | £64.00 | £14.00 |
At 1/5 terms, a placed finish alone returns £14.00 from the £10 total stake, so the place part covers the whole bet with £4.00 to spare. Work out any each way bet.
If a horse at 9/1 is withdrawn
When a horse priced at 9/1 is withdrawn after you've bet on another runner in the same race, Rule 4 takes 10p from every £1 of your winnings. It applies to bets struck at a fixed price before the withdrawal. Work out a Rule 4 deduction.
