At school A, 12 of its 60 students like rock. At school B, 18 of its 120 students like rock. What percentage of students like rock in each school? In which school do you like rock the most?

A = (12/60) x 100 = 20% B = (18/120) x 100 = 15% School A has a higher percentage. Thus, I like school A the most.
