If the ratio of boys to girls is 3:7, this means that for every 3 boys, there are 7 girls. To find out how many boys there are, you would need to divide the total number of children by the sum of the parts in the ratio (3 + 7 = 10) and then multiply that result by the number of boys' parts in the ratio (3). So, if there are 30 children in total, there would be 9 boys (30 divided by 10, times 3).
If boys are first, I'm guessing 3 boys and 2 girls.
90 girls
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.
Yes they are.
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.
2 boys for every 3 girls 8 boys / 2 boys = 4 times the original ratio 4 times original ratio x 3 girls = 12 girls
If boys are first, I'm guessing 3 boys and 2 girls.
3/4 times 48 = 36 girls
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.
The ratio of girls to boys is 21/14 = 3/2 = 1.5 . The ratio of boys to girls is 14/21 = 2/3 = 0.66 .
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)
90 girls
The ratio is 9:12 (girls:boys)Simplified the ratio is 3:4 When there are 24 girls, there will be 32 boys. (3:4 = 24:32)
45 boys are in the class
Yes they are.
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.
The ratio of girls to boys in this scenario is 5:1. This is determined by dividing the number of girls by the number of boys, which gives us 15 girls divided by 3 boys, resulting in a ratio of 5 girls to 1 boy.
