The problem presented in the image asks to find the ratio of girls to boys in a class of 28 students, where there are 19 boys.

Solution:

1. The total number of students in the class is 28.
2. The number of boys is 19.
3. To find the number of girls, subtract the number of boys from the total number of students: $\text{Number of girls} = 28 - 19 = 9$
4. The ratio of girls to boys is therefore 9:19.

Correct Answer:

• The correct choice is 9:19.
