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 of girls to boys in the class can be calculated by dividing the number of girls by the number of boys. With 15 girls and 10 boys, the ratio is 15:10. This can be simplified to 3:2 by dividing both numbers by their greatest common divisor, which is 5. Thus, the ratio of girls to boys is 3:2.
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!
If boys are first, I'm guessing 3 boys and 2 girls.
3 to 4 cuz you would do boys first since its first in the problem
