Answer 17

The key here is to find the link between the English sentences and the math.

First, let's see if we can make sense of this...

"
the ratio of the number of hard cover books to the number of paper back books sold by a bookstore yesterday was 12 to 6.
"

This means that for every 12 hardcover books there were 6 paperbacks.

You could neatly arrange each pile of hardcover and paperbacks like this:
HHHHHH HHHHHH
PPP PPP



(notice how there are 12 Hs and 6 Ps.)

But we can make it even simpler. for every ONE P there are THREE Hs.

So we can split things up like this

HHH
P

So for every 1 P there are three H.

Does this make sense so far? Just in terms of interpreting that first sentence?
