The EURO 2020 / 2021 Favourites. As far as the EURO 2020 / 2021 favourites are concerned, it’s England who are getting the nod at odds of 6.00 with Unibet. You can see why. They went very well in the Nations League, reached the semi-finals of the World Cup and, of course, they would have home advantage with Wembley set to host the semi-finals and final.
Remove 1 from the decimal and convert to a fraction, then reduce to simplest form:
(decimal-1) -> convert to fraction
Examples:
1.75: 1.75 – 1 = .75 = 75/100 = 3/4
2.20: 2.20 – 1 = 1.20 = 120/100 = 6/5
To convert a decimal of 2.00 or higher:
moneyline = (decimal – 1) *100
Examples:
2.00: (2.00 – 1)*100 = 1*100 = +100
3.35: (3.35 – 1)*100 = 2.35*100 = +235
To convert a decimal of less than 2.00:
moneyline = (-100) / (decimal -1)
Examples:
1.9091 : (-100)/(1.9091 – 1) = (-100)/(0.9091) = -109.99 = -110
1.6579 : (-100)/(1.6579 – 1) = (-100)/(0.6579) = -151.98 = -152
Over 1/1: Convert Fraction to Decimal and multiply by 100.
Moneyline = (fraction value)*100
Examples:
7/4: (7/4) * 100 = (1.40) * 100 = +140
6/5: (6/5) * 100 = (1.20) * 100 = +120
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
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
Positive Odds (“+”): Divide the moneyline by 100 and add 1.
decimal = (moneyline/100) +1
Examples:
+100: (100/100) + 1 = 1 + 1 = 2.00
+235: (235/100) + 1 = 2.35 + 1 = 3.35
Negative Odds (“-“): Divide 100 by the moneyline, then add this value to 1.00.
decimal = (100/moneyline) + 1
Examples:
-110: (100/110) +1 = 1 + 0.9091 = 1.9091
-152: (100/152) +1 = 1 + 0.6579 = 1.6579
Positive Odds (“+”): Divide the moneyline by 100 and reduce to simplest form
(moneyline/100) -> simplest form
Examples:
+120: (120/100) = 6/5
+250: (250/100) = 5/2
Negative Odds (“-“): Divide 100 by the moneyline and reduce to simplest form
(100/moneyline) -> simplest form
Examples:
-120: (100/120) = 5/6
-300: (100/300) = 1/3

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.
