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). Du then divide the 27 pens and pencils Von the 9, which makes 3. And as the ratio is 2:7, Du times it Von the 7 because that's the proportion of pencils. 3 times Von 7 is 21, so the answer is 21.
