I'm guessing that's what you mean by 'extracting' 17.5%; the language is vague because when I first read it I wondered if you meant what was left when you take 17.5 of it away and wasn't sure until I noticed Penny Hi Richard. I think you meant to write 5.714 is related to 17.5% Here's what is happening:
So with 14% you do the same thing. But the question becomes this: 14 / 100 = 1 / f multiply both sides by f and we get this: f x ( 14 / 100 ) = 1 now multiply both sides by the reciprocal of what is in parentheses: f x (14 / 100) x (100 / 14) = 1 x (100 / 14) and simplify: f = 100 / 14 in my calculator that means f = 7.143 In fact, you can convert any percentage to this decimal method by So 379.28 x 14% = 379.28 / 7.143.
