Three ways to write the same price
American (+150 / −200) is standard in the US. Decimal (2.50) is used across Europe and exchanges. Fractional (3/2) is traditional in the UK and Ireland.
They all describe the identical payout — just different notation. Decimal is the easiest to do maths with: payout = stake × decimal odds.
