Best ResponseYou've already chosen the best response.1I 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.

Best ResponseYou've already chosen the best response.0to 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
