How to read fractional odds
The first number is what you win and the second is what you stake. Your stake comes back on top when the bet wins, so a £10 bet at 5/2 wins £25 and returns £35 in total. When the first number is bigger, the price is odds-against and you win more than you stake. When it's smaller, the price is odds-on and you win less. When the two are the same, it's evens.
