    1/4 of the course is female.

    Step-by-step explanation:

    Let's call x the number of females on the course ⇒ The number of males would be 3x

    The total number of students would be x + 3x = 4x.

    Based on this, x (the number of females) would be 1/4 of the total students (4x) on the course.
