The 9 students in the Environmental Club represent 25% of the students in the seventh grade. How many students are in the seventh grade?

1 answer

To find the total number of students in the seventh grade, we can use the information that 9 students represent 25% of the total seventh-grade students.

Let \( x \) be the total number of seventh-grade students. According to the problem, 25% of \( x \) is equal to 9 students. We can express this mathematically as:

\[ 0.25x = 9 \]

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

\[ x = \frac{9}{0.25} \]

Calculating the right side:

\[ x = 9 \div 0.25 = 9 \times 4 = 36 \]

Therefore, the total number of students in the seventh grade is \( \boxed{36} \).
