A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results: 80 choose the aquarium.

60 choose the science center.

30 choose the planetarium.

40 choose the farm.

The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium. What is the relative frequency of a student choosing the aquarium? Give your answer as a decimal rounded to the nearest hundredth. Show your work.
