How Do You Convert Fractional Odds to Decimal Odds Manually?

  1. Add the first number (numerator) to the second number (denominator) 
  2. Divide this total number by the denominator (second number)

Here are some examples of converting fractional odds to decimal odds manually:

  • 9/4 fractional odds = 9 + 4 = 13, 13 divided by 4 = 3.25, therefore 9/4 = 3.25 decimal odds
  • 11/4 fractional odds = 11 + 4 = 15, 15 divided by 4 = 3.75, therefore 11/4 = 3.75 decimal odds
  • 7/2 fractional odds = 7 + 2 = 9, 9 divided by 2 = 4.5, therefore 7/2 = 4.5 decimal odds
  • 11/2 fractional odds = 11 + 2 = 13, 13 divided by 2 = 6.5, therefore 11/2 = 6.5 decimal odds

You can now convert sportsbook betting odds between fractional and decimal.
