Using percents… 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.”
Modeling Percent 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 ___
Modeling Percents Use a 10-by-10-square grid to model 26%. A 10-by-10 square grid has 100 squares. 26% means “26 out of 100” or. Shade 26 squares out of 100 squares ___
How are ratios (fractions) and percents related?
How are can percents become fraction 25% So, 25% = ¼
4:5 = what percentage? How do ratios (fractions) become percents?
If you got a 3 out of 10 on the test, did you pass the test? How do you know?
If you scored a 75% on a test, what was your score? How many did you get right and how many did you get wrong?
On your own: Color your Percent Grid You must use between 4 and 6 colors Each small square represents.01 as a decimal Each small square represents 1/100 as a fraction Each small square represents 1% as a percent.
