If there are 55 children in the classroom then it is not possible for 61 of them ti be girls!

4/5 of the children are boys. So 1 - 4/5 ie 1/5 of the children are girls. 1/5 = 100 so 1 = 500 ie there are 500 children in all. 4/5 of 500 is 500*4/5 = 400 So there are 400 boys.

let boys = B and girls = GB +G =120;2G = B;3G = 120;G = 40 and B = 80

If there are four times as many boys as girls, then the ratio of boys to girls is 4:1. To find the number of girls, divide the total number of children by the sum of the parts of the ratio, which is 4+1. So, there would be 30/5 = 6 girls in the group.

275 girls, 325 boys.
