I'm guessing u ment that the ratio was 4:3
so you do 35 divided by 7 (4+3) = 5
4 times 5 =20 (boys)
3 times 5 = 15 (girls)
so there are 5 less girls than boys
12
57 oops ! That's the boys. There are 95 girls.
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
There are 10 students in the initial selection. (7+3) 3 is 30% of 10 and 7 is 70% of ten. 30% of 420 = 126 girls 70% of 420 = 294 boys There are 126 girls at the concert.
75. If the ratio is 3girl per 2boys. Then there's 45girls if there's 30boys...
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.
1515 girls

9 boys
There would be 6 boy students and 18 girl students in the class.

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.
There is 48 Girls and 51 boys
There are 10 students in the initial selection. (7+3) 3 is 30% of 10 and 7 is 70% of ten. 30% of 420 = 126 girls 70% of 420 = 294 boys There are 126 girls at the concert.
