20 percent of x equals 9? - Answers

45. Since 100 times 9 then divided by 20 is 45. From Professor Corey: 45 is correct of course. Another way to figure this kind of problem is to know that 20% is 1/5th of 100 - so 5 times 9 gives you the correct answer as well. If the question was, say, 33% of X = 9, what is X?, then you simply think, "ok, 33 is 1/3rd of 100, so 9 times 3 is...and you'd get 27. The key to these kinds of algebra question is to figure out what fraction of 100 is the percentage part, and then multiply that times the given multiplier (e.g., "9", in this case). Question: 25 percent of X = 13? 25 = 1/5 of 100 ; 5 * 13 = 65 It's easy once you know the process.
