### Katherine Nicolasora's Proportion Post

PART I

RATIO: a comparison of two quantities that have the same unit of measure.

RATE: a comparison of two quantities that have different units of measure.

PROPORTION: an equation which states that two ratios are equal.

PART II

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 III

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

PART V

1). No, it is not fair.
2). This does not seem just and fair.
3). This isn't fair because the homeless man stole only \$100 and he was sent to prison for 15 years, meanwhile the CEO was sent for only 40 months in prison over a \$3 billion fraud.
4). If I were the judge, I would have sentenced the CEO, Paul R. Allen, for at least 20 years in prison since \$3 billion is a huge amount of money. As for the homeless man, Roy Brown, I sentence him to about a month -or less- in prison. Because, yes he did turn himself into the police and gave the \$100 bill that he stole back, but what he did was still not right. Stealing is still a crime.

PART VI

Question: How tall are the trees surrounding the boy?

I searched up what the average boy's height was online. It says that the average height for 12-13 year old boys (the boy looks around that age to me) is around 62 inches, or 5'2 feet. I used my fingers to figure out how many boys I needed to get to the top of the trees. About 3 boys that are stacked on top of each other is equivalent to the height of the trees. So, 5.2 x  3 = 15.6  (5x3=15 and 2x3=6).
So, my estimate is that the trees surrounding the boy are approximately 15'6 feet tall.
