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

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
57 oops ! That's the boys. There are 95 girls.
the ratio is 3:5 what you do is make a fraction out of it (18/30) and then reduce and put a colon in it
1 to 2 = 5 to 10 so 15 students in all.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
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.
13 to 17
42:31
30 students per teacher maximum
3 to 5
1515 girls
There would be 6 boy students and 18 girl students in the class.

50 students
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.
