Hi all,
Does anyone know how to work this out?

What i have is $100.00 to spend on a race
and i want to spread it over lets say three runners.Its a form of dutch betting but instead of a target amount to bet into im intrested in how much of a percentage/ return I will get after ive spread the money over the three runners.
So i might have a 5% gain or 20%
Hope that makes sense..
Example;
2.7
3.5
4.7
Whats the formula to spread the $100.00 over these three runners?
