Question

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.

Answer 1

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.
