### Aaron's Proportion Post

Proportion
-An equation which states that two ratios are equal.

Ratio- A comparison of two quantities that have the same unit of measure.

Rate- A comparison of two quantities measured in different units

1. 5 hours to travel 360 miles is about 72 mph

2. As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with. It would be 200ml.

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

1) multiply top left to bottom right
multiply bottom left to top right

2) divide top left by bottom left
divide top right by bottom right

3) times top left with a number to make top right
times bottom left with a number to make bottom right

1) Does this seem fair?
No it doesn't seem fair.
2) With what you know about proportion look and read what is in the image above. Does it seem just and fair? Why have you made this choice?
No it still doesn't still seem fair. For someone to steal \$3 000 000 000 and get prison for 3.5 years is ridiculous, also for someone to steal \$100 and go to prison for 15 years is more ridiculous. Most Unfair Thing To Do!!!
3) What would you have done if you were the judge?
If I was judge I would give him about a week of Community service.
or
I would let him in jail for 1 month.
