In a certain class the ratio of men to women is 3:5. If the class has 24 people in it, how many are women?
Correct answer: C. 15
- A. 9
- B. 12
- C. 15
- D. 18
Explanation
The ratio 3:5 contains 8 total parts, so each part represents 24 people / 8 = 3 people. Women represent 5 parts, giving 5 x 3 = 15 people. Students may choose 18 by multiplying 24 by 3/4 instead of using the women-to-total ratio 5/8.
