Question

a school principal ordered s new electric pencil sharpeners. each classroom received 2 of them. write an expression that shows the number of classrooms.

Explanation:

Step1: Identify the relationship

We know that the total number of sharpeners (s) is equal to the number of classrooms times the number of sharpeners per classroom (2). Let \( n \) be the number of classrooms. So, \( s = 2\times n \).

Step2: Solve for the number of classrooms

To find \( n \), we divide both sides of the equation \( s = 2n \) by 2. This gives us \( n=\frac{s}{2} \).

Answer:

\(\frac{s}{2}\)
