Jasmines Proportion Post

Part 1
Rate-compares 2 quantities measured in different units

Proportion- two equivalent statements 


Ratio- a comparison of 2 quantities  that have the same unit of measure 


Games to help you with ratio, rate and proportion...

Videos to help you with rate and proportion... 

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 

1. you can find the common denominator 
2. see if its divisible 
3. multiply it by each other

3/4=12/16 is TRUE
4/9=16/32 is FALSE 


Part 4 





Part 5

1. Does this seem fair?
No, this is not fair what so ever.  

2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair?
I don't clearly understand the question.. but it still isn't right.

3. Why have you made this choice?
I have made this choice because it clearly isn't fair.. All though he stole money(which isn't right) he does not deserve to got to jail longer than the man who stole $3b... plus, he may have stole... but clearly told the woman why he was stealing.. and he also told the police the next day. 

4.What would you have done if you were the judge?
If I were the judge.. I would only sentence the man for 2-3 months in jail.. other than 15 years! As for the other man.. I would put him into jail for longer than 15 years. After that has been done, to avoid homeless people stealing again I would look towards helping them out. For example... free health care or doctors to look at homeless people. Or even small sandwiches to fill the stomachs of hungry people.

Using the man in the picture.. how many of him can you use to measure the tree?
By measuring the man with a ruler.. I got 2 inches.
The tree it self is 5inches... 
Since 2 is not divisible by 5.. the man will have to be cut in half.
2 full men, and one man who is cut in half.
