Part 1- Definitions

Rate- Comparison of the two quantities measured in different kinds of subjects, such as kilograms, hours, grams etc.

 A guy ran 22 laps in 7 minutes.  How many will he run in 14 minutes?
 Ratio- It's a relation between two quantities.

Soda's to Oranges     Oranges to Soda's
3:2                            2:3
  







Proportion- It is two equivalent fractions, ratios, and rates


 I ate 10 chocolate bars in 40 minutes.
My proportion is that i ate 1 chocolate bar every 4 minutes.









Part 2- The questions

A) 6 hours to drive 240 hours is 40 km/h










B) Emma saves 28 cents of every dollar that she earns. Emma earned $75 last week. How much money did Emma save last week?








Part 3- Equivalent ratio statement

3/4=12/16

































4/9=16/32

Part 5-


      
  1. Does this seem fair? 
  2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair? 
  3. Why have you made this choice? 
  4. What would you have done if you were the judge?
Answers
1. It does not seem fair because he didn't take a very large amount of money he also plead to guilty and gave the money back. The CEO should've been charged with the 15 years because they took a way larger amount.
2. Not at all because he only took a $100 and he got charged with a bigger punishment. (15 years in jail) But the CEO took 3 billion and only got charged 3 months.
3. I made this choice because 15 years is way too much to charge a homeless man for taking $100 he needed the money to eat, he had no money to stay anywhere, and he needed it to go to the detox center.
                                                                    4. If I was the judge i would have switchd up the years around so Roy would only stay 4 months in jail for taking $100, and the CEO would stay 15 years in jail for taking 3 billion dollars.
