Sportsbooks quote the same price three different ways. American odds (−110, +150) are standard in the US, decimal odds rule everywhere else, and fractional odds still show up in horse racing and UK books. Underneath all three is the number that actually matters: the implied probability — how often the bet must win for the price to break even.
Use this to translate any price instantly, and to build the habit that sharp bettors swear by: thinking in probabilities, not prices. A −110 line is not "close to even money" — it is a demand that you win 52.4% of the time.
