Three Formats, One Sportsbook Line
American odds dominate US sportsbooks — a negative number shows what you'd wager to win $100, while a positive number shows what a $100 bet returns. Decimal odds, common on the MLB Baseball Odds Board and Boxing Team Form Guide markets, multiply your stake by a single number to get your total return. Fractional odds express profit as a ratio, so 5/1
means five dollars back for every one dollar risked. All three formats describe the same underlying probability. Knowing which one you're looking at stops you from misreading a line and placing the wrong size wager.
