Three possibilities are: 11 and 13 , 7 and 17 , 5 and 19.
1 to 2 = 5 to 10 so 15 students in all.
There would be 6 boy students and 18 girl students in the class.
45
It is 8 : 26.
3 boys to 7 girls is 3 boys per 10 students gives class size of 13 too small; 6 boys per 20 students gives class size of 26; 9 boys per 30 students gives class size of 39 too many; class size is 26
There are 18 girls and 6 boys in the class of 24 students
1 to 2 = 5 to 10 so 15 students in all.
There would be 6 boy students and 18 girl students in the class.
18 boys and 12 girls

It is 8 : 26.
3 boys to 7 girls is 3 boys per 10 students gives class size of 13 too small; 6 boys per 20 students gives class size of 26; 9 boys per 30 students gives class size of 39 too many; class size is 26
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
60%
If there were 30 students in the class, it would mean that 2/5 are girls. Girls = 12. Boys = 18
14 boys are in the class
