Decimal To Fraction Odds
By convention only a set of fractions are used in fractional odds betting markets. The set does not include exact mathematical equivalents to all possible decimal and American odds. We use the closet fraction that is used in betting markets.
Decimal Odds Eg. 3.00 (equivalent of 2/1). Multiply the odds by the stake to work out the total return. For example a £100 bet which won at 3.00 will give a profit of £200 and a total return of £300. Decimal odds are displayed as a number greater than one, usually with up to two decimal points (1.10, 1.90, 4.50, etc). Decimal - 1 divided by the decimal odds, multiplied by 100 to give a percentage e.g. Decimal odds of 2 = (1/2). 100 = 50%. Fraction - 1 divided by (the fractional odds plus 1), multiplied by 100 to give a percentage. Fractional odds of 3/1 = (1 / ((3/1) + 1)). 100 = 25%. American: Positive odds - 100 divided by (the american odds plus. Under 1/1: divide -100 by the Fraction as a Decimal. Moneyline = -100/(fraction value) Examples: 1/4: -100/(1/4) = -100/.25 = -400 1/10: -100/(1/10) = -100/.1 = -1000. Fractional to Decimal. Convert the fraction to a decimal and add one. Examples: 3/4: (3/4) + 1 = (.75) + 1 = 1.75 6/5: (6/5) + 1 = (1.20) + 1 = 2.20. American to Decimal.
For example, the exact mathematical equivalent of decimal odds 30 is fractional odds 29/1. However 29/1 is not used in betting markets, instead 30/1 is used, so that is what appears in this converter.
