Once you've practiced and mastered multiplication and division using fractional notation, refer back to the mathematical application on page 83 and think about how you can apply your skill to real data. What if Liz and her road crew were to paint every mile of interstate highway running through your home state; how much time would it take?

Here's your chance to explore the World Wide Web and apply your new skills at the same time. Follow some related Web sites to find the total miles of interstate highway within your state, or other interesting facts about the road.

After you've practiced and after you've explored, don't forget about your upcoming Chapter Test. Prepare for your exam by working through our Chapter 2 Review, and then check your answers. These free downloadable files are accessible by selecting the Chapter Review button at the top of this page.

Good luck!
