There are three common methods of presenting odds that most bookmakers support.

Implied Probability % is also useful when evaluating a bet.

Fractions

Used mainly in Ireland and the United Kingdom, fractions quote the potential profit should the bet win, relative to the stake. For example if £10 is bet at odds of 2/1 the potential profit is £10 (£10 x 2) and the total returned is £20 (£10 plus the £510 stake).

Decimals

Decimals quote the potential return should the bet win, relative to the stake. For example if $10 is bet at odds of 3.00 the total returned is $30 ($10 * 3) the potential profit is $20 ($10 x 3 minus the $10 stake).

American

Positive figures: The odds state the winnings on a $100 bet e.g. american odds of +110 would win $110 on a $100 bet.

Negative figures: The odds state how much must be bet to win $100 profit e.g. american odds of -90 would win $100 on a $90 bet.

Implied Probability

Odds correlate directly with probability –  e.g a 2/1 bet is expected to win one in every 3 attempts, hence the probability is 33%.
