 katiecain said: Okay, I think this is right, but I don't do Maths anymore (I'm at college) so its been a while. So the ratio is 2:7. That makes 9 parts (2+7=9). あなた then divide the 27 pens and pencils によって the 9, which makes 3. And as the ratio is 2:7, あなた times it によって the 7 because that's the proportion of pencils. 3 times によって 7 is 21, so the answer is 21.

 camosolidsnake said: The ratio is 2 pens to 7 pencils, Right? Okey that means for every 2 pens, あなた get 7 pencils. 2+7=9 , 27/9=3 . That means あなた get 6 pens and 21 pencils. I could be wrong , but then again I wa..... JOHNSON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
