In the UK, odds are usually offered either as decimals or as fractions. You can often choose the format in which you receive odds in your Account section of the betting site, or in the Settings. When odds are given as decimals, this means you multiply your stake by this amount to determine the return. For example, if Team A are set at 2.00 to win, a stake of £10 would return £20. With regards to fractions, you multiply your stake by the fraction, and then add on your original stake to calculate the total return. For example, if odds of 4/1 are given, that means £10 would return a total of £50.
