Annie does a survey of the sixth-grade classes to see who prefers pretzels to goldfish. In Miss Johnson's class, 1/6 of the students preferred goldfish. In Mr. Feldstein's class, 2/3rds of the students preferred goldfish. In Ms. Henderson's class, 1/5 of the students prefer goldfish. If each class has 30 students, how many people total prefer goldfish?
How many students are in Mr. Feldstein's class? ** First find the number of students in Mr. Feldstein's class who prefer goldfish: 2/3 * 30 students = <<2/3*30=20>>20 students
How many students are in Mr. Feldstein's class? ** Then find the number of students in Mr. Feldstein's class who prefer goldfish: 1/6 * 30 students = <<1/6*30=5>>5 students
How many students are in Ms. Henderson's class? ** Then find the number of students in Ms. Henderson's class who prefer goldfish: 1/5 * 30 students = <<1/5*30=6>>6 students
How many students total prefer goldfish? ** Then add the number of students from each class who prefer goldfish to find the total: 20 students + 5 students + 6 students = <<20+5+6=31>>31 students
