girls = 15
boys = 42 - 15 = 27
ratio of girls to boys = 15/27
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
The ratio is: 3 to 4
Of the total 15 people 5 are boys and 10 are girls Boys are 5/15 = 1/3 Girls are 10/15 = 2/3 Ratio of boys to girls is 1 to 2
for every one boy there are five girls
There is approximately 3 ways to write this ratio out. Those ways are of the following: 1. 15:9 2. 15 to 9 3. 15 over 9 (as if it is in a fraction)
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.
25 If the ratio is 5 boys to 8 girls, there are 25 girls and 15 boys in the class. To solve for girls, multiply 40 x 5/8. Then subtract the girls from 40 to find how many boys.
1 to 2 = 5 to 10 so 15 students in all.

6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
The ratio is: 3 to 4
Of the total 15 people 5 are boys and 10 are girls Boys are 5/15 = 1/3 Girls are 10/15 = 2/3 Ratio of boys to girls is 1 to 2
number of boys = ratio of boys x total strength / total ratio = 5 x 27/9 = 5 x 3 = 15 number of girls = ratio of girls x total strength / total ratio = 4 x 27/9 = 4 x 3 = 12 verification: 15 + 12 = 27
10 to 15 or 2 to 3 even
5 girls to 1 boy

There is approximately 3 ways to write this ratio out. Those ways are of the following: 1. 15:9 2. 15 to 9 3. 15 over 9 (as if it is in a fraction)
