Fractional Odds

How To Convert Decimal Odds To Fractional There are two steps to convert decimal odds into a fraction. Step 1) Convert decimals odds into a fraction by subtracting 1, and using 1 as the denominator. Example: 3.40 – 1 = 2.40. Fractional Odds are used in the world's largest bookmakers and most commonly in UK.

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.

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.
