To find out how many students attend the school in total, you can set up a proportion based on the given information:
272 (students who walk to school) is 21% of the total number of students (let's call it "x").
So, you can write the proportion as:
272 / x = 21 / 100
Now, you can solve for x:
272 * 100 = 21 * x
27,200 = 21x
Now, divide both sides by 21 to find x:
x = 27,200 / 21
x ≈ 1,295.24
So, approximately 1,295 students attend the school in total. Since you can't have a fraction of a student, you can round this to the nearest whole number. Therefore, approximately 1,295 students attend the school.
