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)
100 boys

A ratio of boys to girls was 3 to 7 and there were 200 more girls than boys there would of been 150 boys that enrolled in school this year. This is a math problem.
3/4 times 48 = 36 girls
100 boys
There is 48 Girls and 51 boys

2 boys for every 3 girls 8 boys / 2 boys = 4 times the original ratio 4 times original ratio x 3 girls = 12 girls
160 boys. 162 boys.

190 girls
Using the ratio provided, since the ratio of girls to boys is 7 to 5, the total ratio can be calculated as 7 + 5 = 12. Since there are 275 boys, the number of girls can be calculated as (7/12) * (275) = 159.375, which rounds to 159 girls.
If boys are first, I'm guessing 3 boys and 2 girls.
90 girls
