Most UK on-line bookies show odds in the traditional format such as 1/2, 11/8, 2/1 etc. Some bookmakers use decimal format e.g 1.5, 2.38 etc. Whichever format you are using it is easy to calculate your winnings. It is just a matter of using the appropriate method.
Traditional: Left Hand Figure, Divided by the right hand figure and then multiplied by the stake so for a 50pts stake.
1 / 2 X 50 = 25 pts return, you will also get back your stake of 50 pts making 75 altogether.
Decimal: 1.5 X 50 = 75 - 50 (original stake) = 25pts
It is easy to convert the traditional format to a decimal!
So using our above example, just divide 1 by 2 then add 1:
1 / 2 + 1 = 1.5
