15% of the students in mrs. madison’s math classes have an ‘a’. if 18 students have an ‘a’, how many students are in mrs. madison’s math classes? [type your answer as a number.]

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Ithink ghe answer to this question is b just trying to others
