Jammelle's Propotion Post

Part 1
-Ratio- a pair of numbers but a different units.

-Rate-Compares two numbers measured in different units. (No example )
-Proportion- a relationship that says that ratio and rate are equal.

Part 2
1.   5 hours to travel 360 kilometers is about _____km/h.
My answer is 72. because i divided 360 by 5 :)

2.   Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week?
Emma saves $ 21. 00 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
a.) 3X6 = 48
b.) 12X4 = 48
c.) Cross multiplying 

Part 4
Find a video about using proportion and embed it in your post.  Make sure you select the small size of the video. (Bonus Marks if you make your own video about proportion and embed it)

Part 5

1.Does this seem fair? i think its not fair.
2.With what you know about proportion look and read what is in the image above.  Does it seem just and fair? NO
3.Why have you made this choice? because its unfair, because CEO stole 3 billion dollars but it was only sent to jail for 40 months and  The homeless man stole $100 dollars and got sent to jail for 15 years and it is 180 months. 
4.What would you have done if you were the judge? not going to send him for 15 years.
