A class has a ratio of males to females of 3 to 5. If there are 24 students in total, how many of them are female?

Explanation

The ratio of men to women is 3:5, meaning for every 3 men, there are 5 women. The total parts in the ratio are 3 + 5 = 8 parts. Since the class has 24 students, each part represents 24 ÷ 8 = 3 students. Therefore, the number of women is 5 parts × 3 = 15. Hence, there are 15 women in the class.
