How to Convert Fraction Odds to Decimals

Convert a fraction odd into a decimal odd by dividing the first number (the numerator), by the second number (the denominator), and adding 1. Equation: (numerator/denominator) + 1 = decimal odds Example: 6/5 is equal to 2.20. Divide 6 by 5. This equals 1.20. Add 1, and you had the decimal 2.20.

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.  This creates the decimal odds of 2.40/1. While this is a perfectly good fraction, bookmakers never use numbers with decimal points in fractionals. That is why we need step two. Step 2) We now need to turn this fraction into its most simple form. Find the nearest whole integer (i.e. no decimal place). The factor to which you need to multiply the numerator to the whole integer is reflected in the denominator. Example: You need to multiply 2.40 by 5 before it becomes a rounded number, 12. Therefore the fraction becomes 12/5. (2.40 x 2 = 4.802.40 x 3 = 7.20, 2.40 * 4 = 9.60, 2.40 * 5 = 12)

How to Work Out Implied Probability From Fractional Odds

Divide the second number (denominator) by the total of the first number (numerator) and second number (denominator). Equation:  Denominator / (numerator+ denominator ) * 100 = implied probability Example: 4/1 implied probability can be calculated as 1 / (4+1) * 100 = 20%

How to Work Out Implied Probability From Decimal Odds

Divide 1 by the decimal, and multiply it by 100%. Equation:  (1/ decimal odds) * 100 = implied probability Example: 1 /4.00 * 100 = 25% Find other bet calculators and interesting offers, like the bet365 bonus code, on mybettingsites.co.uk
