To find 90 percent of a number, multiply the number by 0.9. In this instance, 0.9 x 600 = 540. Therefore, 90 percent of 600 is equal to 540.
15%
% rate:
= 90/600 * 100%
= 0.15 * 100%
= 15%
600 x .15 = 90$ now subtract 90$ from 600$ and you get 510$
15% of 600 = 15% * 600 = 0.15 * 600 = 90
90% decrease

1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
600 multiplied by 90 is 54,000.
