Second number / first number * 100 = %



Example, odds of 15/8 for Sophie


8 / 15 * 100 = 53%


Odds of 5/2 for Siavash


2 / 5 * 100 = 40%


And so on. That should give you a comparative number to work with. If theres no second number, use 1.


Example, odds of 10 for Charlie

1 / 10 * 100 = 10%
