Why the Conversion Messes Up Your Bet
Look: you see a decimal odd, you think “easy,” but the math hides a trap that bleeds profit.
From Decimal to Fraction – The Quick Switch
Here is the deal: take the decimal, subtract 1, then turn the remainder into a fraction.
Example: 2.75 becomes 1.75/1 = 7/4, a 7 to 4 payoff.
Turning Fractions into Percentages
And here is why it matters – percentages let you compare any market instantly.
Take that 7/4, divide 7 by 4 = 1.75, multiply by 100 = 175%.
Converting to American Moneyline
By the way, the US loves moneyline.
If the decimal is above 2, subtract 1, multiply by 100, you get a positive moneyline.
If below 2, do 100 divided by (decimal-1) and make it negative.
2.50 → (2.5-1)×100 = +150. 1.80 → -100/(1.8-1) = -125.
Common Pitfalls
Never round too early – a .01 shift can flip a bet from profit to loss.
Don’t forget to re-add the stake when you calculate returns; many miss that step.
Tool Time
Speed is king. Use a spreadsheet or a calculator that handles the chain: decimal → fraction → percent → moneyline.
