a class of 25 students has 10 boys. Three boys have braces and 4 girls have braces..what is the ratio of boys with braces to boys in class
3:10
There are 12 boys.
45 noys
In 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)
3+7=10 (3 and 7 are both ratio numbers) 420/10=42 (10 is the sum of both ratio) 3x42=126 girls (3 is ratio of girls) 7x42=294 boys (7 is ratio of boys)
3:10
The ratio is 94:141
45 boys are in the class
The ratio of girls to boys in Charlotte's class is 3:2. This is found by dividing the number of girls by the number of boys to get 21/14 = 3/2.

It is 10:3, as stated in the question!
3 to 4 cuz you would do boys first since its first in the problem
If boys are first, I'm guessing 3 boys and 2 girls.
