Question

Mr. Shaffer has approximately 130 different students throughout the day. This is about 20% of the total number of students in the school. Find the approximate number of students in the school.

Answer 1

The approximate number of total students in the school is 650.

Explanation:

Here, given the number of students with Mr. Shaffer has = 130 students

Let us assume the total number of students in the school = m

Now, given: 20 % of total students in the school = 130

⇒ 20 % of m = 130

`\implies (20)/(100) * m = 130\\ \implies m = (130 * 100)/(20)  =  650`

or, m = 650

Hence the approximate total number of students in the school is 650.
