  6. Homework Answers

  7. Proportion Race • Each group will get a stack of proportions • You must find each missing value • Then, you must put them from least to greatest based on the missing value

  8. Word Problem Pass • Each group will be assigned one word problem • In your groups you must: • Show your proportion • Show work to show answer

  9. Percent

  10. What is percent? Most states charge sales tax on items you purchase. Sales tax is a percent of the item’s price. A percent is a ratio of a number to 100. You can remember that percent means “per hundred.” For example, 8% means “8 per hundred,” or “8 out of 100.”

  11. Splost • If a 1% sales tax goes to SPLOST that means: • For every $1.00 you spend, you pay $0.01 to splost. • For every $10.00 you spend, you pay $0.10 in sales tax. • For every $100 you spend, you pay $1 in sales tax. Because percent means “per hundred,” 100% means “100 out of 100.” This is why 100% is often used to mean “all” or “the whole thing.”

  12. Group Activity Each group must make the most create a sign that reads: % equals ratio of a number to 100

  13. 17 ___ 100 Visual Representation Use a 10-by-10-square grid to model 17%. A 10-by-10 square grid has 100 squares. 17% means “17 out of 100” or . Shade 17 squares out of 100 squares.
