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.
If the ratio of girls to boys is 5 to 4, this means that out of every 9 students (5 girls + 4 boys), 5 are girls and 4 are boys. To find out how many girls there are in the class, you need to divide the total number of students by the total parts of the ratio (5 + 4 = 9) and then multiply that result by the girls' portion of the ratio (5/9). So, in this case, there would be (5/9) * 90 = 50 girls in the class.

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.

18 boys and 12 girls
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.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
1 to 2 = 5 to 10 so 15 students in all.
If the ratio of girls to boys is 5 to 4, this means that out of every 9 students (5 girls + 4 boys), 5 are girls and 4 are boys. To find out how many girls there are in the class, you need to divide the total number of students by the total parts of the ratio (5 + 4 = 9) and then multiply that result by the girls' portion of the ratio (5/9). So, in this case, there would be (5/9) * 90 = 50 girls in the class.
It is 8 : 26.
Well, isn't that a happy little math problem! If the ratio of girls to boys is 5 to 4, that means for every 5 girls, there are 4 boys. To find out how many girls in a class of 108 students, we first need to divide 108 by the total parts in the ratio (5+4=9), which is 12. Then, we multiply 108 by the girls' share (5/9) to find there are 60 girls 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.
