It’s an antiquated, confusing and often inprecise system that could easily be translated into % chance of winning.
It has to do with is you put up X amount of $ (the second number) if you win you get Y amount in winnings (the first number).
Odds almost always though come with a share for the house, which should never be part of the equation unless one is going through a bookie.

The formula:
Fractional odds
Fractional odds are generally the most traditional form of expressing betting odds. They are a simple reflection of the return you will receive for a particular amount bet. So for example, the odds of 5/2 (expressed as 5 to 2) means that for every 2 units that you bet, you will receive 5 back.
To convert fractional odds into their respective probabilities, we make the following calculation.
So in our example of odds of 5/2.
Implied probability = 2 / (5 + 2)
Implied probability = 2 / 7
Implied probability = 0.286
Multiplied then by 100 to express as a implied probability percentage of 28.6%

Curiously, football better has gone more into the line (the favorite and the margin of victory) because it puts everything into a 50% level of likelihood, much easier to understand.
I am a strong advocate of translating into % chance because it is much easier to grasp, and expresses the relationships among the contenders much more clearly. And you can be sure the person creating the odds actually comes up to 100%, which as I said quite often odds don’t do.

This is the first time I’ve understood what they mean. It’s actually so simple.

Damn, dude. You must be a math wiz.
