  3. Let’s Review 60% = 60 percent = 60 for every 100 A percent is a part-to-total ratio where the second number is always 100.

  4. Let’s Review 5 ways to solve a ratio problem 1) Table with addition 2) Table with multiplication 3) Double number lines 4) Tape diagrams 5) Graphing

  5. Thinking that a ratio describes just one situation Example: 1 pink sweater for every 5 sweaters 1 out of 5 is pink. 2 out of 10 are pink. 3 out of 15 are pink.

  6. In the mall parking lot, 60% of the cars are blue. If there are 240 blue cars in the parking lot, what is the total number of cars? KNOW Percent: 60 for every 100 cars are blue. Part: 240 blue cars CALCULATE Total: ??? cars

  7. KNOW Percent: 60 for every 100 cars are blue. Part: 240 blue cars CALCULATE Total: 400 cars 0 60 120 180 240 0 100 200 300 400 blue cars total cars

  8. 240 0 60 120 180 0 100 200 300 x4 blue cars total cars 400 x4

  9. In this lesson you have learned to calculate the total when you know the percent and the part by using a double number line.

  10. In Nick’s baseball card collection, 40% of his cards are players on the Washington Nationals team. He has 10 Washington Nationals baseball cards. What is the total number of cards in his collection?
