My question is: The ratio of boys to girls in a math class is 5:8. How many girls are in the class if the total number of students in the class is 260? Your thoughts:
If the ratio of boys to girls in the math class is 5:8, the total ratio of the number of boys and girls in the math class is 5 + 8 = 13. The fraction that represents the number of boys in the class is 5 / 13, and since there are 260 students in the class, the number of boys in the class is 5 / 13 * 260 = 100. The number of girls in the class is 260 - 100 = 160. The final answer: 160.
