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.

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

Step-by-step 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

or, m =  650

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