The ratio of the number of girls to the number of all students in the class is 4 to 9. Are there more boys or more girls in that class?

If there are 4 girls to every 9 students, then there are 5 boys to every girl, 9-4=5. So, there are more boys in the class.
If there is a ratio of girls to the whole class/the boys and that ratio is 4:9, and the 4 represents the girls that means there are 5 boys.There for there are more boys than there are girls.
