(a) The ratio of new books to used books is calculated as follows:

First, find out how many used books there are. We know there are 11 books in total and 6 of them are new. So, the number of used books is 11 - 6 = 5.

The ratio of new books to used books is then 6 to 5, or 6:5.

(b) The ratio of used books to all books on the shelf is calculated as follows:

We already know there are 5 used books and 11 books in total.

So, the ratio of used books to all books is 5 to 11, or 5:11.
