Question

In an elementary school, 20% of the teachers teach advanced writing skills. If there are 25 writing teachers, how many teachers are there in the school?

Answer 1

125

Explanation:

To find the total number of teachers in the school, we can use the information given. We know that 20% of the teachers teach advanced writing skills, and there are 25 writing teachers.

To find the total number of teachers, we can set up a proportion using the percentage and the actual number of teachers.

Let "x" represent the total number of teachers in the school.

We can set up the proportion as follows:

20/100 = 25/x

To solve for "x", we can cross-multiply and then divide:

20x = 100 * 25

20x = 2500

x = 2500/20

x = 125

Therefore, there are 125 teachers in the elementary school.
