Where the dialects show up on this site
UK tickets speak fractional with decimal in brackets; our US pages speak American because their small print does; Germany is decimal-native. The spec tables always print the bar in the offer's own dialect. This page is the translator.
Reading a price as a probability
Divide stake-share by total return: 1/2 means risking 2 to win 1, so the market rates it 2-in-3 (66.7%), before the bookmaker's margin is baked in. That margin is why implied probabilities across a match sum past 100%. You don't need the maths to claim a free bet; you need it the day you start believing a price is 'generous.'
The mistake everyone makes
Misreading the min-odds bar in the wrong dialect — 1/2 (1.5 decimal) is a LOW bar most sensible bets clear; 2/1 (3.0) is a real one that short favourites fail. One glance at the decimal column above settles any offer's bar in seconds.
Frequently asked
What do odds of 1/2 mean in decimal?
1.50 — stake £10, get £15 back in total (£5 profit). It's the most common minimum-odds bar in UK welcome offers, and comfortably above the price of most short favourites, which is the whole point.
