∙ 13y agoIn a class of 30, if there are 12 boys then there must be 18 girls. This would make the ratio: 18:12 or 3:2 (girls:boys)
Ok, if there is one girl to every nine boys, there are 10 kids in all. that means that if there are 2 girls, you have to double 9, making 18, adding up to 20. . so, 2 girls and 18 boys. If there are 4 girls, then multiply 9 times 4. 4x1 and 4x9. and then you get your answer.
No.
Assuming that any given student must be either a boy or a girl (that is, no student can be neither a boy nor a girl), then 17 is sufficient. With sixteen students, you could have 8 boys and 8 girls, so there wouldn't be nine of either; adding the seventeenth student will push one or the other group to nine.
Put none in the first room, then 1 in the second, 2 in the third, 3 in the fourth... and so on until there are 8 in the ninth room. Room boys total # 0 ...... 0 # 1 ...... 1 # 2 ...... 3 # 3 ...... 6 # 4 .... 10 # 5 .... 15 # 6 .... 21 # 7 .... 28 # 8 .... 36

2 boys for every 3 girls 8 boys / 2 boys = 4 times the original ratio 4 times original ratio x 3 girls = 12 girls

A girls' locker room and boys' locker room both are common in many ways with size, appearance, etc. However, the only difference perhaps is the scent of both male and female.
The issue is that boys and girls can lie
You enter the sewer through the restrooms in the park (boys use the boys' room, girls use the girls' room).

Boys are not allowed in the girls' locker room.
