78 students 10 of them are freshmen what fraction of the class are freshman

10/78 = 5/39

To find the fraction of the class that are freshmen, you need to divide the number of freshmen by the total number of students.

In this case, there are 78 students in total, and 10 of them are freshmen. The fraction is calculated by dividing the number of freshmen (10) by the total number of students (78):

Fraction of freshmen = number of freshmen / total number of students

Fraction of freshmen = 10 / 78

Since this fraction cannot be simplified, the fraction of the class that are freshmen is 10/78.
