Abhi's proportion post.


1)Ratio - A pair of numbers that compares different type of units. 


2)Rate - Compares two quantities measured in different units.

 3)Proportion - Is the equation that shows two ratios that are equal.


 1) 5 hours to travel 360 kilometers is about _____km/h

 First I divided 5 by 5 to get 1 Then i divided 360 by 5 to get 72.

72km/per hour

2) Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week?




What are the three ways you can prove that equivalent ratio statements are true?

 3/4 = 12/16  or 4/9 = 16/32

1. Using time table

2. Dividing it

3. Multiplying it

Part 4

Part 5

1. Does this seem fair?
 No it isn't fair.
2.With what you know about proportion look and read what is in the image above.  Does it seem just and fair? 
100 dollars for 15 years? Too much. It should be about few thousand or tens of thousands to be 15 years. So no, it does not seem just or fair. 

3.Why have you made this choice?  

Because 15 years is way too much for 100 dollars, and that guy was homeless now I feel bad for him. 

4.What would you have done if you were the judge? 

I would let him in jail for a week or so, because he only stole 100 dollars, and he gave it back and admit he stole it.


bonus question



 How tall are the trees?
I guessed that this guy is about 5.3 then i stacked the guy till i reached the top of the trees which was three stacks.
 5.3x3=15.9. so the trees must be 15.9 ft tall.
