How I Stopped an Alien Invasion Using Proportions

heeeeeeeeey guuuuuuys x)

ALIEN STORY: A group of aliens came to our planet Earth because they couldn't do proportions and they were jealous . So they came here to invade us and learn how . Then a group of intelligent students saved our earth by using proportions . Yippee !

So yea, the math homework was that we were suppose to pick 3 questions from pages 67, 68 or 69 . I chose questions: 18, 19 and 20 on page 68 .

18) At an amusement park, a new thrill ride was introduced . It costs $7.50 for 3 rides on the Wild Slider .
18a) What is the Wild Slider's unit rate per ride ?

18b) At this rate, what would it cost for 18 rides on a Wild Slider ? Determine the answer in two different ways .

19) Determine the missing value in each equivalent fraction .


20) A breakfast cereal contains corn, wheat, and rice in the ratio of 3 to 4 to 2 . If a box of cereal contains 225 grams or corn, how much rice does it contain ?
