## Honors Algebra 1: Calculations, Ratios, Percent & Proportions - Chapter Summary and Learning Objectives

The ability to calculate ratios, percents, proportions and rates has broad applications far beyond the classroom. It's something we do every day, whether we actually think about it or not. Any time you shop, you're looking for sales, which means you'll be calculating the percentage off the purchase price offered by the discount. You pay taxes on whatever you buy, and the bank pays you interest on the money in your accounts. Thus, percents, ratios, rates and proportions are all facts of life. Check out the video lessons for more information on the following:

• Defining rate, ratio, proportion and percent
• Performing calculations with distance and time
• Understanding and figuring taxes and discounts
• Identifying the difference between a ratio and a proportion
