About This Set
These 25 questions test the basic method for each type in the chapter: conversions and percentage with ratio, percentage change and successive change, the product rule with income and savings, and the applications from elections to mixtures. They come in mixed order, so for each one first ask what the 100% is. Give yourself about 20 minutes and finish all 25 before reading any explanation. Under 20 right means some basics still need work: go back to the section for each question you missed before Practice Set 2.
