The best way to fully understand what a question is asking for, is to read that question over, paying attention to EACH WORD. Along the way you should be asking yourself "what does this word stand for? Why is it used here?".

And of course, you should be acquainted with the topic of a question.

For example, let's take a look at the statement of this question:

"For any positive

*x* and

*y* if

*x*/

*y* is

*n*% of

*y*, then what percent must x be of y?"

**positive ***x* and *y* - means that

*x* and

*y* are unconditioned, but positive real numbers

*x*/*y* is *n*% of *y* - means that

*x*/

*y* = (

*n* / 100) ×

*y*THE MAIN QUESTION:

**what percent** -

means to find the number ___%. **percent ... x be of y** - means

*x* × (___% / 100%) =

*y*.
