Real World Ratios

Using the Internet, find six examples of ratios. (You may want to start at http://mathforum.org/library/topics/ratio/.)

What are the different ways ratios are verbally expressed or symbolically represented in each example? Does each ratio describe a part-whole relationship (the size of a part compared to its whole), a whole-part relationship (the whole compared to a part of the whole), a part-part relationship (one part of a whole compared to another part), or a rate (one quantity compared to a different quantity)?
