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.

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.
