Given that the ratio of male students to female students in a philosophy class is 3 : 5, say there are 3x male students and 5x female students; thus, there are 3x + 5x = 8x students. So, we have 8x = 40 => x = 5; thus, there are 5x = 5*5 = 25 female students.BTGmoderatorDC wrote:If the ratio of male students to female students in a philosophy class is 3:5, and there is a total of 40 students in the class, how many female students are in the class?
