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.
20
Expressed as a percentage, 9/20 x 100 = 45 percent.
9% of 27 = 0.09 x 27 = 2.43
To find 20 percent of a number, multiply the number by 0.2. In this instance, 57.00 x 0.2 = 11.40. Therefore, 20 percent of 57.00 is equal to 11.40.
The easiest way to do this is to use the following:is over of = percent over 100Just substitute x for what the unknown is, then cross multiply. In this case:Re-wording the original question: (60 is ) (20 percent) (of what)?60/x = 20/100Cross multiply - 20x = 6000x = 300
9 x 20 = 180
20/x = 9 Divide each side by 20. you get 1/x = 9/20. flip both sides. you get x = 20/9

x = 20
It is: 20% of 1875 = 375.
Expressed as a percentage, 9/20 x 100 = 45 percent.
If 30 percent of 360 = 108 then 108 multiply by 20% = 540 therefore, 20 % of 540 = 108 X = 540
x = -9
20 percent of 1000000 dollars is 20/100 x 1000000 which equals 20000
20% = 20/100 = 0.220 percent of 1202.5 = 1202.5 x 0.2 = 240.5
Expressed as a percentage, 20/45 x 100 = 44.4 recurring (that is, 44.4444...) percent.
9% of 27 = 0.09 x 27 = 2.43
