Answer
Attempt 1 out of 2

Answer 1

Let \( x \) be the total number of students in Ridgewood Junior High School. According to the problem, 25% of the students brought their lunch, which is represented mathematically as:

\[
0.25x = 46
\]

To solve for \( x \), divide both sides of the equation by 0.25:

\[
x = \frac{46}{0.25}
\]

Calculating the right side:

\[
x = \frac{46}{0.25} = 46 \times 4 = 184
\]

Thus, the total number of students in Ridgewood Junior High School is \( \boxed{184} \).
