Answer 2

Calculating the Number of Girls in the Class

To calculate the number of girls in the class, we can use the given ratio of boys to girls, which is 8:5, and the total number of students in the class, which is 26.

Step 1: Calculate the total number of parts in the ratio. The total number of parts in the ratio of boys to girls is 8 + 5 = 13.

Step 2: Calculate the number of girls. To find the number of girls, we can use the following proportion: 8 parts (boys) = 26 students 1 part = 26 / 8 = 3.25 students 5 parts (girls) = 5 * 3.25 = 16.25 students

However, since we can't have a fraction of a student, we need to adjust the number of girls. Since the ratio is 8:5, we can adjust the number of girls to be a multiple of 5 that is closest to 16.25. The closest multiple of 5 to 16.25 is 15.

Therefore, there are 15 girls in the class.
