Randolph's Propotion Post

Task 1 
Ratio: A comparison of two or more quantities with the same unit; for example, in the following diagram, the ratio of black squares to white squares is 2 to 3. 
Ex. 2 to 3, 6:9, 6/9



 Rate: A ratio that compares two quantities measured in different units.
Ex.  15 to 20, 15:20
Proportion: An equation that says that two ratios or two rates are equal.

Task 2
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.


Task 3
What are the three ways you can prove that equivalent ratio statements are true?
3/4=12/16 diagonally, multiply top left and bottom right, vertically, and horizontally.

Task 4
Here is a video to help you guys out!...

Task 5
1.) Does this seem fair?
      Not it is not fair at all.

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?
      It is not fair because he fraud $3.5 billion and the judge let him go to jail for just only 3 years but the other guy stole but it gave it back and got surrounded by the police and the judge gave him 15 years in jail.

3.) What would you have done if you were the judge?
      If I was the judge, I would charge him for took $3 billion dollars and he would go to jail for 15 years and the homeless guy that he stole $100 dollars and he would returned to jail for only 3 years.
