**Reiny**, Tuesday, January 1, 2013 at 10:37pmnumber of boys ---- b

number of girls ----- g

(2/7)g = (3/5)b

g = (3/5)(7/2)b = 21/10 b

g - b = 165

21b/10 - b = 165

21b - 10b = 1650

11b = 1650

b = 150

g = 21/10(150) = 315

150 boys, 315 girls, total of 465

check:

(2/7)(315 = 90

(3/5)(150) = 90

yeahhh
