Question

the school chorus has 52 students, which represents 26% of the seventh graders. How many students are in the seventh grade

Answer 1

Set up a proportion, where x = the total number of students in 7th grade:


`(52)/(x)=(26)/(100)`

Then, cross multiply and solve for x:


`(52)/(x)=(26)/(100)\\26x=5200\\26x/26=5200/26\\x=200`

Therefore, there are 200 students in the 7th grade.
