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

8. 2:3 is the original ratio, high fiber:high protein. 2 x 3 48 = 32 48 / 3 x 2 = x, x =

9. 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 =

28. 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
