  1. Aim # 12: How Are Fractions, Decimals, and Percents Related? A New Approach?

  2. Do Now Divide accordingly:

  3. Do Now = 0.421052 . . . Divide accordingly:

  4. Do Now = 0.421052 . . . Divide accordingly: = 0.2

  5. Do Now = 0.421052 . . . Divide accordingly: = 0.2 = 0.04

  6. Do Now = 0.421052 . . . Divide accordingly: = 0.2 = 0.04 = 0.35

  7. Do Now = 0.421052 . . . Divide accordingly: = 0.2 = 0.04 = 0.35 = 0.0825

  8. Do Now = 0.421052 . . . Divide accordingly: = 0.2 = 0.04 = 0.35 = 0.3333 . . . = 0.0825

  9. Do Now = 0.421052 . . . Divide accordingly: = 0.2 = 0.04 = 0.35 = 0.3333 . . . = 0.6666 … = 0.0825

  10. Minilesson: A commercial states “14 % of the dentists interviewed recommend Pest Toothpaste.” That means 14 out of every 100 recommend the toothpaste.

Percent comes from “per cent” meaning “per every hundred” [Like dollars per pound, mph, etc.] The word “cent” is found in our money system (a great analogy for percent.” The word “cent” is found in the words century and centimeters.

  12. Minilesson (con’t): In general Percent means “what part of one-hundred”

  13. Minilesson (con’t): You convert fractions to N/100 by converting the original fraction to an equivalent fraction with denominator of 100. X 5 = 15 % X 5

  14. Minilesson (con’t): You convert fractions to N/100 by converting the original fraction to an equivalent fraction with denominator of 100. X 12.5 = 12.5 % X 12.5

  15. HW # 12 Due Monday Answer the following word problem, and then the questions listed in our textbook. While playing the game of Monopoly, Joseph saw that he had $2,743 in his account consisting of a certain number of each of the following denominations: $500’s, $100’s, $20’s and $1’s.
