Debt reduction plan interest rate question? - credit card interest rate reduction

I'm trying to establish a plan to reduce debt, whether a credit balance with the highest interest rate, then switch to the next highest, etc. My question is, what have I to my credit card interest rates for this priority? There is an annual percentage rate and the proportion of cash and then I think there's another one. In one of my cards as they range from 8% to 29% depending on whether we observe. It is a pity that I am an idiot when it comes to these things! Thanks for any help ...
