What are proportions?  The number of one thing as compared to the number of others

How many pages are there to the number of minutes from the data we are given?
40 pages and 1.6 minutes.  How do we express that as a proportion?

The proportion is the same so as we change the number of minutes we also have to change the number of pages so we have the same proportion.  This lets us setup and equation where we can solve for the number of pages in proportion to 5 minutes.
