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.

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

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.
