The answer is 640 because if you multiply the total student of 6h grade by 100 and divide by 30. You will get the total of student in the school

I believe the answer is 640 students. To get this answer you need to divide 192 by 30% in decimal form so it would look like 192/0.30 and that should get you 640 students!!!
