Big Picture
What this problem is really about
First translate the story into a part-to-whole fraction, with twelve selected students above eighteen total students. Then we’ll divide both parts by their greatest common factor and check that the reduced numerator and denominator share only one. That preserves the class share and guarantees simplest form.
