Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Katika darasa la Bwana Feldstein, 2/3 * 30 = <<2/3*30=20>>20 wanafunzi wanapendelea goldfish.
Katika darasa la Bi Henderson, 1/5 * 30 = <<1/5*30=6>>6 wanafunzi wanapendelea goldfish.
Katika darasa la Miss Johnson, 1/6 * 30 = <<1/6*30=5>>5 wanafunzi wanapendelea goldfish.
Jumla ya idadi ya wanafunzi wanaopendelea goldfish ni 20 + 6 + 5 = <<20+6+5=31>>31.
