### Part 1

Ratio - is a comparison of quantities that have the same units.

Rate - comparison of two quantities measured in different units.

Proportion - is a relationship that says two ratios or rates are equal.

### Part 2

1. 5 hours to travel 360 kilometers is about _____km/h.
2.  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

What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16  or 4/9 = 16/32

### Part 4

Find a video about using proportion

### Part 5

1. Does this seem fair?  No, I don't think it's fair.

2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair?  No it is not fair.

3. Why have you made this choice? I've made this choice because if you read it again the CEO stole \$3 billion and was sentenced to jail for 40 months while the homeless man robbed \$100 and was sentenced for 15 years. If you change 15 years to months it would have been 180 months. The CEO stole more money and yet the homeless man was sentenced to jail longer. I just don't think the judge is being fair.

4. What would you have done if you were the judge? If I were the judge first I would investigate and ask them why they stole or robbed money, maybe they have a valuable reason why they did. Then I would look at the amount of money they stole or robbed. I would then give them a fair period of time they would be staying inside the jail.
