Re: PS - y is what per cent of x (OG11) [#permalink]

I just came across this question in the book.
I just think that this is a real confusing question. It is not difficult, but the way they want you to set it up and to translate the question into an equation is contradictory to their other similar percentage problems (I don't have the exact examples off the top of my head).
To me "x is m percent of y" translates to x/y = m100 (not m/100). Meaning when x divide y, you get a decimal number (could be greater than or equal to or less than 1), you multiply that number by 100 to get the "percent" annotation.
I know that the OA is E, but the OG explanation is not consistent with their other "percentage" setups.
