Question

dumbcow · Answer

8/11 = x/30
cross multiply

myininaya · Answer

or...
b=boys
g=girls
b+g=30
and
b/g=3/8 assuming its boys to girls and not girls to boys
you have two equations and two unknowns 
have fun!

what? this makes no sense lol there are decimals in the answers! haha

myininaya · Answer

i know i see this you have 240/11 girls lol

anonymous · Answer

don't you think something is wrong with the data in the question? 30 is NOT divisible by 11

anonymous · Answer

all i know is i wish my classes had a boy to girl ratio of 3:8  *wink*

anonymous · Answer

correct the question to something like "the ratio of boys and girls IS 3:7" then you would get an answer.

anonymous · Answer

240/11 girls....1 girl is a midget...she counts as 0.818 of a girl...therefore, 21 normal girls, 1 midget girl, 8 boys....problem solved.  =D
