Fifteen students in the band play clarinet. These 15 students make up 12% of the band. Your friend uses the proportion 12/100=?/15 to find the number of students in the band. Explain why your friend is incorrect and use the grid to find the correct answer.
He or she is wrong because the total number of students that are in their band class is NOT 15, since it tells us that the /fifteen students who play clarinet make up 12% of the band. So it should be 12/100=15/? Then, you can find out the answer.
