total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
5:4
Total students = Girls (12) plus Boys (18) equal 30 ie Girls (12) divided by total Students (30) = .40 multiply by 100 to get percentages =40 %
12 boys, 15 girls The composite numbers bit is irrelevant. b+g=27 g-b=3 add the equations b+g+g-b=27+3 2g=30 g=15
9 to 12 is the ratio. BUT, if you simplify it (divide them both by the same number which makes both of them come out to a whole number) it's 3 to 4
There are 12 boys.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
18 boys and 12 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.
12:4
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)
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 answer is 8/12.
7:6 (girls to boys)
In a class of 30, if there are 12 boys then there must be 18 girls. This would make the ratio: 18:12 or 3:2 (girls: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
