I would suggest you just write all the information down and it will make more sense. Like, write what you know. Then, write an equation to help you solve. I would help you with this, but I gtg. Just try writing it out yourself more simply, that often helps. The solving will be easy.

to begin, A = 1/8 A a boys joined A 32/4 = 8, so 8A boys joined the group.so, A = 1/8 A b girls joined B So, now there are B+b = 1/3(9A) = 3A 5/2 A + b = 3A b = 1/2 A b = 1/2 * 1/8 a = a/16 example: A=12 B=30 A/4 = 3, so 3*32 = 96 boys joined A, making 180 boys in all B+b = 108/3 = 36 so, 6 girls joined, or 96/16
