Question

Sally’s dance school had 60 students last year. This year there are only 48 students enrolled. By what percent did the enrollment decrease?

Answer 1

-20%

My brain is weird on how i figure it out but I divided 48 by 60 and got .80 so i just got the other whole to make it 1 so it is 20%. This is not the correct way to do this but this is how i got my answer.
