Question

A decade ago, the average class size at Newton Middle School was 30 students. Now it is 30% smaller. What is the average class size currently?

Answer 1

Answer: 21 students

Explanation:

A number being 30% smaller means that it has reduced to 70% of its original size.

This means we can multiply the original value by its new percentage, 30x0.7=21 students.

Answer 2

21 because you would multiple 30 by .7
