Okay. So, 3 of 15 students like reggae, and you're trying to find out how many like reggae music out of 180 students. You could set up a proportion to solve this, or to do this in a different way, do 180/15 to get 12. Multiply that times 3 in order to get 36. Out of 180 students, about 36 students at Henry's school like reggae. The answer is 36.
