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.

How do you convert percent to a ratio?
Ratios are good for comparing two quantities. Like in a classroom, the ratio of girls to boys, for example. Say the class has 40 students, and 22 of them are girls, so this is 22/40 = 55% of the class. But the ratio is comparing the girls to the boys, not the entire class. So if there are 55% girls, then 100% - 55% = 45% boys. Now the ratio can be made of 55 : 45 girl to boy ratio. This can be simplified to a 11:9 ratio.
