8/1, 15/2, Evens. What the numbers mean, and how they map to decimal.
A fraction is profit over stake. 8/1 pays £8 profit for every £1 staked. Win, and £9 comes back: the £8 profit plus your £1 stake.
15/2 is the same idea. £2 staked wins £15 profit. Evens is 1/1: stake and profit match.
Decimal odds are the total return per £1, stake included. 8/1 becomes 9.00. Evens becomes 2.00.
The conversion is one sum: add 1 to the fraction. 15/2 is 7.5, so 8.50.

Tradition. UK bookmakers grew up on fractional boards and most still default to them. Exchanges and most betting tools use decimal, because two decimal prices compare at a glance.
