total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
If there are 24 girls in a class of 50 and we assume the remaining students are boys, then there are 26 boys and the ratio of boys to girls is 26boys/24girls = 13/12=1.08333 boys for each girl.
18 boys and 12 girls

13 to 17
To find the ratio of the number of girls in the band to the total number of students, first calculate the total number of students: 17 boys + 12 girls = 29 students. The ratio of girls to the total number of students is 12 girls to 29 students, which can be expressed as 12:29.
42:31
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
3 to 5
Since the ratio of boys to girls is 5 to 8, the total ratio parts is 5 + 8 = 13. To find how many boys are in the class, divide the total number of girls (40) by the total parts of the ratio (13), then multiply by the number of boys parts (5). Thus, there are 15 boys in the class.
