Answer provided by our tutors
Let
m = the number of male students
f = the number of female students
The ratio of male students to female students at a certain university is 11 to 16:
m : f = 11 : 16 cross-multiply
16m = 11f
There is a total of 32,400 students:
m + f = 32400
by solving the system of equations:
16m = 11f
m + f = 32400
we find:
f = 19,200 female stundets
m = 13,200 male students

There are 19,200 female students and 13,200 male students.
