In a school there are 122 grade 8s, 105 grade 9s, 134 grade 10s, 109 grade 11s, 90 grade 12s. Express Each Class as a percentage of the whole school.
Answered by Ms. Sue
Add up the numbers to find the total number of students in the whole school.

Divide the number in each class by the total. Multiply the decimal answer by 100 to get the percent.
