Q. All students in Ridgewood Junior High School either got their lunch in the school cafeteria or brought it from home on Tuesday. 25% of students brought their lunch. 50 students brought their lunch. How many students in total are in Ridgewood Junior High School?Answer:
Understand Relationship: Understand the relationship between the percentage of students who brought their lunch and the total number of students. The problem states that 25% of students brought their lunch, and we know that 50 students represent this 25%. We need to find the total number of students.
Set Up Equation: Set up the equation to find the total number of students.Let the total number of students be represented by T. Since 25% of T is equal to 50 students, we can write the equation as:0.25×T=50
Solve for T: Solve the equation for T.To find T, we divide both sides of the equation by 0.25:T=0.2550
Perform Calculation: Perform the calculation to find the total number of students. T=0.2550T=200
Verify Solution: Verify that the solution makes sense.If 200 students are in the school and 25% brought their lunch, then 200×0.25 should equal the number of students who brought their lunch, which is 50.200×0.25=50This confirms that our solution is correct.
