Task 5
Does this seem fair?
No
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, because the homeless guys just stole $100 while the Ex- Mortgage dude has $3b.
The Ex-mortgage should be in prison for 15 years than the homeless guy
What would you have done if you were the judge?
The homeless guy will be in the community center helping there for a year or 2.
I would also thank him for honest. And for the Ex-mortgage dude, I will sentence him in prison for 20 years.
a ratio is a relationship between two numbers of the same kind
A value describing one quantity in terms of another quantity.
A proportion is an equation with a ratio on each side.
1. 5 hours to travel 360 miles is about _____mph

3. What would you have done if you were the judge?
Jayjay's Proportion Post
3/4 = 12/16 or 4/9 = 16/32
2) you can do it vertically.divide the numerator to the denominator for each ratios.
3) you can do it vertically. you divide top and bottom from left to right
--------------------------
1) Ratio- Ratio is a relationship between two numbers that are the same.
2) Rate- Rate is a ratio that compares two amounts of different units.
3) Proportion-A proportion is an equation with a ratio on each side.

3/4 = 12/16 or 4/9 = 16/32
3/4=12/16 is true because 3 times 16 is 48 and 4 times 16 is 48.
--------------------------
Does this seem fair? No because this homeless dude only stole $100 and turned himself in and has to stay in prison for 15 years. The rich guy stole 30 million dollars and has to stay in prison for ONLY 1 year, or something like that.

1. Does this seem fair? No.
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?
I think it's not fair because the rich guy stole $3 billion and he just need to spend a 3 years. While, the homeless guy will spent time in jail for 15 years even though he just stole $100 and he turned himself in.
3.What would you have done if you were the judge?
If I were the judge, I will give the homeless man 1 year in the prison or give him community work every day for 2 months.
