Kassey's proportion post

Task 1.
 Ratios

 Three-term: compares three quantities measured in the same unit.

Part-to-Part ratio: compares different parts of a group to each other.

Part-to-whole: compares one part of a group to the whole group.


Rates:
    A comparion of two quantities measured in different unit.

Task 2.


1
1. 5 hours to travel 360 miles is about 72m 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.
Answer: 200ml







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


Answers:
1. first, you can do it horizontally. What you do is you divide or multiply the top left to the top right and do the same thing at the bottom.


2. Next, you can do it vertically . What you do is you can divide or multiply the top left then the bottom left and do the same thing to the opposite side.


3.Finally, you can do it diagonally. What you do is you could dive or multiply the top left and the bottom right and then do the same thing to the top right and the bottom left.

Task 4.
Hope you enjoy the proportion video.








Task 5.


1.Does it seem fair?
NO, it doesn't seem 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? 
No it's not fair because this man who stole $ 3 billion dollars only is in jail for 40 months. Then this other guy gets 15 years in prison for stealing $100 dollars and bringing it to the police and saying"I did it."


3.What would you have done if you were the judge?
 I have made this choice because the man who stole $ 100 should have only been in jail for like 1 week, and the other guy should of gotten 20 years in prison.
