    On a scientific calculator you just have to express the numbers in scientific notation: a K = 10^3, a billion is 10^9. Then you say 300x10^3 ÷ 9.2 x 10^9. That gives you the ratio, multiply that by 100 to give you a %age.

    Or if you have a plain calculator or are doing it by hand: express the numbers in equal powers of ten:
    300k = 300 x 10^3 = 0.3 x 10^6
    9.2B = 9.2 x 10^9 = 9200 x 10^6
    Now you can just say 0.3 ÷ 9200, then x 100 for a %age. (Or use the calculator % key if you have one.)

    You are the type of what the age is searching for, and what it is afraid it has found. I am so glad that you have never done anything, never carved a statue, or painted a picture, or produced anything outside of yourself! Life has been your art. You have set yourself to music. Your days are your sonnets.

    Not sure how much precision you need in the answer, but 0.00326 would be a more accurante value - see here (the 'e' symbol is short hand for 'exponential' and it just means "multiply by ten to the power of").

    I'm so used to using software that I just threw in "^" meaning "to the power of" without explaining that. Programs like Excel also use "*" and "/" instead of "×" and "÷" , because there are no "×" and "÷" keys on the keyboard. So "e" is short for "*10^". :cool:
