Percent of a number using fractions
The way I learned it is you say

5 is to 12% as x is to 100%

or

5/12 =x/100

or

(5/12)*12=(x/100)*12

or

5=12x/100

or

5*100=(12x/100)*100

or

500=12x

or x= 500/12

or x = 125/3

Translation:
"is" = "="
"of" = "*"
"%" = "*0.01"

Relation:
5 = 12*0.01 * x

x = 125/3 (approximately 41.667)

Re: [SOLVED] Percent of a Number
If 100% is the most of anything you can acquire, then if 5=12% , then 1% = 5/12 , thus, 100% is 5/12 * 100 = 46.6666 ...

Don't mean to upset you SelfTaughtMaths, but this question was asked 7 years ago! If they don't know how to do it by now, there's no hope!!

Acknowledged, however, the purpose of my post was not only for a different explanation on said method, but it was for perspective members as well, who may also want to know how to calculate percentages , and to have a look at this thread instead of posting a new one and cluttering up the system with the same question.
