  4. As chimps go up one, fiber goes up 2 cups, & protein goes up 3 cups.

  5. 2:3 is the original ratio, high fiber:high protein. 2 x 3 48 = 32 48 / 3 x 2 = x, x =

  6. 2:3 original ratio of high fiber:high protein 2/5 is the fraction of the mix that is high fiber 2 x 5 125 = 50 125/5x2 = x, x =

  8. 1. 6:4 or 3:2

  9. 6 x 21 = 126 4 x 21 = 84

  10. 18 / ? = 3, ? = 6 108/6 = 18 72/6 = 12

  11. 3 2 is a part to part comparison 3 5 is a part to whole comparison Lamar is correct.

  17. 7. No. If you put everyone in the stadium in groups of 14, 9 would be men and 5 would be women.

  18. B. 5 x 1.8 = 9

  19. No. The statement means 4 out of every seven people surveyed were watching the super bowl.

  20. Football, the ratio is 6:1 Soccer 80 x 225 250 60 x 225 250 85 x 225 250 = = = i. x 67 x 94 x 89 Football Basketball Soccer 30 x 160 240 10 x 160 240 120 x 160 240 = = = ii. = = x 180 = x 15 x 45

  21. Period Boys Girls 1 2 3 4 12 8 7 6 17 5 12 4 Write a difference between 1st period's girls & boys. Write a ratio of girls to boys in 2nd period. What percent of period 3 are girls? Write a fraction of girls to class members for 4th period. 17 - 12 = 5, 5 more girls girls:boys, 5:8 7 + 12 = 19, 12 / 19 x 100 is about 63% 6 + 4 = 10, 4/10 are girls
