Your answer would be 18.00%, because 18 is not a decimal, and you add .00 at the end of it to make it an official percent.
The word "percent" means "out of a hundred." Therefore, all you need to do to find out what percent 18 is of 100 is set up a proportion like so. [tex] \frac{18}{1}= \frac{x}{100} [/tex]
