HELP ME Twelve out of the first 100 people who entered the mall were wearing glasses. If this sample is representative of 550 people who entered the mall, about how many of them will probably be wearing glasses?
So, we write a fraction, which would be 12/100. Then we would do 12/100 = x/550. You could divide 100 by 550, which is 5.5. Then we would multiply 5.5 by 12, which is 66. So 66 people would be wearing glasses.
