Question

You asked 75 randomly chosen students how many movies they watch per week. 21 students said they don’t watch movies. If there are 1200 students at your school, how many would you predict don’t watch movies?

Answer 1

Answer: 336 students

Explanation:

We can set up ratios. Let x be the number of students that are predicted to not watch movies.

21/75 = x/1200

We can now cross multiply:

25200 = 75x

x = 336 students
