  1. Today we will interpret percent as a part of a hundred. interpret– figure out; understand percent– per one hundred (100) Concept

  2. When you take a test your score is shown as a percent.For example, lets say you take a math test that has 100 questions on it. If you score 70 correct, your percentage would be 70 %. APK

  3. Percentmeans per hundred. It is another way of saying, “out of one hundred.” Percent CD

  4. Definition “Cent” is a Latin root word which means 100. • Many words have come from the root cent such as: • century • centimeter • centipede • cent CD

  5. One hundred 100 CD

  6. CD

  7. 100 pennies = $1.00 CD

  8. More examples • $ .50 is ½ of a dollar • 50% means ½ $1.00 50¢ 50¢ = + CD

  9. 50 100 1 2 Money & Percents Fraction Simplified Percent Decimal Fraction 50% .50 = = = CD

  10. 100 books! I have read 95 books out of my 100-book- collection. 95 % CD

  11. 20 out of 100 = 20% or CD

  12. 40 out of 100 = 40% Or CD

  13. 50 out of 100 = 50% or CD

  14. 10 out of 100 units are shaded blue. 10 100 = 10 % CD

  15. 30 out of 100 units are shaded blue. 30 100 = 30 % CD

  16. 80 out of 100 units are shaded blue. 90 100 = 90 % CD

  17. Why is understanding percentimportant? • You will know the relationship between any numberand 100as a percent. • You will know how a percent translates into fractions. • What are other reasons why it is important to know how to understand IMP

  18. If 24 out of 100 units are shaded blue. _24_ 100 = __ % What is the Percentage? GP

  19. If 32 out of 100 units are shaded blue. _32_ 100 = __ % What is the Percentage? GP

  20. If 16 out of 100 units are shaded blue. _16_ 100 = __ % What is the Percentage? GP

  21. what is 55 % of 100? 55 GP

  22. what is 75 % of 100? 75 GP

  23. what is 45 % of 100? 45 GP

  24. what is 100 % of 100? 100 100 100 = 1 x 100 GP

  25. How we are going to interpret percent as a part of a hundred. • Look at the diagram representing 100 • Count the shaded boxes inside the 100’s chart • Write the answer in fraction form and percentage There are 10 boxes shaded! = 10%=
