Once you've practiced and mastered decimal notation, think about how you can apply your skill to real data. Refer back to page 193, the first page of Chapter 4, in your Basic Mathematics textbook and review the casual dining application. Americans are eating more meals in restaurants instead of at home. Are all Americans eating out more. Some more than others? Where do you fit in to the American dining-out trends?

Here's your chance to explore the World Wide Web and practice your new skills at the same time. Follow some related Web sites that discuss dining trends and menu prices using many different numeric notation, including decimal notation.

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 4 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!
