Question from a math genius.

[KKsuited]

How do I convert percentages to odds. If a flush draw is 35% on the flop, how do I convert that to odds. It's around 5-1 on the flop, then close to 5-1 on the river, but how do I arrive at the odds of the flush hitting on either the flop or turn?

I actually have a master degree in business, but I must have slept through some math classes.
