The village was polygot. If the ratio of bilingual denizens to trilingual denizens was 14 to 3 and the denizens totaled 3,400, how many were trilingual?
Can you tell me whether I am doing this right or not?
My work:
T/D
T/3,400 = 3/3,400
T3,400 = 3,400*3
T3,400 = 10,200
T3,400/3,400 = 10,200/3,400
T=3
I keep coming back to the answer already given for trilinguals. I don't think that I am coming up with the correct answer. Can you please show me what I am doing wrong (if I am doing anything wrong at all). Thank you so much!
