**Steve**, Friday, March 2, 2012 at 10:45amto begin, A = 5/2 B

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 1-8 boys in all

B+b = 108/3 = 36

so, 6 girls joined, or 96/16

**Steve**, Friday, March 2, 2012 at 10:47amsorry about the mistyped capitalization. The lines in error should read

a = 1/8 A

and

b = 1/2 * 1/8 a = a/16

and there are 108 boys at the end, not 1-8
