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? Give me reasons, before answering the question
First find the number of students in Mr. Feldstein's class who prefer goldfish: 2 / 3 * 30 students = 20 students. Then find the number of students in Mr. Feldstein's class who prefer goldfish: 1 / 6 * 30 students = 5 students. Then find the number of students in Ms. Henderson's class who prefer goldfish: 1 / 5 * 30 students = 6 students. Then add the number of students from each class who prefer goldfish to find the total: 20 students + 5 students + 6 students = 31 students. So the final answer is 31.
