Answer: 180 students
Step-by-step explanation:
To find out how many students are in the seventh grade, we can set up a proportion based on the information given.
Let x represent the total number of students in the seventh grade.
Given that 9 students represent 5% (5/100) of the total number of students in the seventh grade:
[tex]\dfrac{9}{x} = \dfrac{5}{100}[/tex]
Cross-multiply:
5x = 900
Divide both sides by 5:
x = 180
