Riding on a school bus are 20 students in 9th grade, 10 in 10th grade, 9 in 11th grade, and 7 in 12th grade. Approximately what percentage of the students on the bus are in 9th grade?

20/45 = ?

Wouldn't it be 20/46?
Since 20+10+9+7= 46 which is the total of students.
And since you are trying to find what percentage of them are 9th graders it's 20.
So 20/46= 0.43 which is 43%
So the answer is 43% of the students on the buss are 9th graders.
