Boys have to be either 3, 6, 9, or 12 because you have to be able to take 2/3 of them and get a whole number. The number of girls for each of these cases is 10, 7, 4, 1. You have to be able to take 1/4 of this number and also get a whole number, 4 is the only one that works so girls that love math is i/4 of 4, or 1.
