If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?
To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.
The fraction
represents the number of students who passed the exam out of all the students.
To find out what percent of the students passed, we can turn

3^x * 1/27
10 * 1/27
10/27
