What Fractional Odds means
Fractional odds, most associated with UK bookmakers and horse racing, express profit as a fraction relative to your stake. Odds of 7/5 mean $7 profit for every $5 wagered - a $50 bet would profit $70 (plus the $50 stake returned). Fractional odds can look confusing next to American or decimal formats because the fraction itself doesn't map cleanly to a $100 baseline, which is part of why they've largely fallen out of favor at US-facing sportsbooks even though horse racing markets still use them heavily.
