Middle school students were asked how they got to school each morning. There were 120 students who said

they walked to school. This number represents 30% of the school enrollment. How many students are
enrolled?

Answer 1

Answer: 400

Explanation:

n = 400

if we choose n as the number, we write are able to write an equation, or number problem.

30% of n = 120

now solve.

first we need to convert 30% to fraction form, which is 30/100.

the reciprocal of 30/100 is 100/30. now multiply 120 by 100/30

(120 x 100) / 30 = 400!
