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)
There are 10 students in the initial selection. (7+3) 3 is 30% of 10 and 7 is 70% of ten. 30% of 420 = 126 girls 70% of 420 = 294 boys There are 126 girls at the concert.
3:10
The ratio is 94:141
45 boys are in the class
There are 12 boys.

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.

2 to 3
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.
