All students in Ridgewood Junior High School either got their lunch in the school cafeteria or brought it from home on Tuesday. 10% of students brought their lunch. 48 students brought their lunch. How many students in total are in Ridgewood Junior High School?

Answer 1

Let \( x \) be the total number of students at Ridgewood Junior High School.

We know that 10% of the students brought their lunch, and we have the information that 48 students brought their lunch. We can set up the equation as follows:

\[ 0.10x = 48 \]

To find \( x \), we can solve for it by dividing both sides of the equation by 0.10:

\[ x = \frac{48}{0.10} \]

Now, calculating the right side:

\[ x = 48 \div 0.10 = 48 \times 10 = 480 \]

Thus, the total number of students in Ridgewood Junior High School is

\[ \boxed{480}. \]
