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.

total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
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.
1 to 2 = 5 to 10 so 15 students in all.
It is 8 : 26.
If the ratio of girls to boys is 5:4, then out of the total of 108 students, 5/9 are girls and 4/9 are boys. Therefore, the number of girls is 108 x (5/9) = 60.
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
13:27 There are 13 boys and 27 students (13 boys and 14 girls, 27 students total) in the class, so the ration is 13 to 27. Since this ratio cannot be reduced any further, the answer is simply 13:27.
