Twenty-five percent of the students at Marcus Garvey Middle School bring their lunches from home. 225 students do not bring their lunch. How many students attend the school? Draw and label a diagram to show the number and percent of each group of students. Homework Help ✎

Since 25% of the students bring lunches from home, then 75% of the students must not bring their lunches to school.
If 225 is 75% of the students, how many total students attend the school and how many bring lunches from home?

After finding out each value, create a diagram to illustrate this ratio.
