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

If the ratio of boys to girls is 3:7, this means that for every 3 boys, there are 7 girls. To find out how many boys there are, you would need to divide the total number of children by the sum of the parts in the ratio (3 + 7 = 10) and then multiply that result by the number of boys' parts in the ratio (3). So, if there are 30 children in total, there would be 9 boys (30 divided by 10, times 3).

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

72 girls and 18 boys for a total of 90.

Let the number of girls be represented by x. Since there are twice as many boys as girls, the number of boys would be 2x. Therefore, the total number of children is x (girls) + 2x (boys) = 60. This simplifies to 3x = 60. Solving for x, we get x = 20. So, there are 20 girls in the group of 60 children.
