The ratio of girls to boys is 21/14 = 3/2 = 1.5 .
The ratio of boys to girls is 14/21 = 2/3 = 0.66 .
35%
The ration of girls to boys is 21:6To simplify this divide both numbers by 3 = 7:2
14 boys are in the class
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
There are 21 boys. Boys = 30% Girls = 70% = 49 40/.7 = 70 70 - 49 = 21
21:14 21/7:14/7 3:2
21 to 14
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
The ration of girls to boys is 21:6To simplify this divide both numbers by 3 = 7:2
21 boys + 14 girls = 35 studentsThis also works for math and social studies classes.
14 boys are in the class
Yes it is good but for boys you have to be 14-21 to get clothes and girls about 11-21
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.

B/G = 4/3 so 3B = 4G B+G = 21 Multiply by 3: 3B+3G = 63 But 3B = 4G so 4G+3G = 63 ie 7G = 63 so that G = 9 So B+G=21 means B = 12 3 more boys so B' = 12+3 = 15 1 more girl so G' = 9+1 = 10 So new ratio = B'/G' = 15/10 = 3/2 or 3 to 2
