The entire school would be 100%. Therefore 32+35=67. 100-67=33. 33% are eighth graders
there are 33% 8th graders
At Marble Middle School, 33 percent of the students are 8th graders, calculated by subtracting the percentages of 6th and 7th graders from 100 percent. This was done by adding the percentages of the other grades and then finding the remainder. Hence, 8th graders make up 33% of the school's population.
