2.20: 2.20 – 1 = 1.20 = 120/100 = 6/5
Decimal to American
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
Fractional to American
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
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
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

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:
