girls = 15
boys = 42 - 15 = 27
ratio of girls to boys = 15/27
If the ratio is 5:4, and the number of pupils is 27, this means that there are 5 + 4 = 9 ninths to the whole. Therefore, 5/9 x 27 is equal to 15 and 4/9 x 27 is equal to 12. There are therefore 15 girls and 12 boys.
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
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.
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)
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.
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.
1 to 2 = 5 to 10 so 15 students in all.

To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.
If the ratio is 5:4, and the number of pupils is 27, this means that there are 5 + 4 = 9 ninths to the whole. Therefore, 5/9 x 27 is equal to 15 and 4/9 x 27 is equal to 12. There are therefore 15 girls and 12 boys.
The ratio is: 3 to 4

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.
10 to 15 or 2 to 3 even
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
5 girls to 1 boy
