Jeremy's Proportion Post

Ratio - The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Ex. 6 to 9, 6:9, 6/9

Rate - A comparison of two quantities measured in different units.

Ex. 15 to 20 or 15:20

Proportion - An equation which states that the two radius are equal.

1) 5 hours to travel 360 miles is about 72 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.

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

3/4 = 12/16

You can multiply the top left number to the bottom right number. You can also do it diagonally, horizontally , and vertically.

5) 1. Does this seem fair?

I don't think this is 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. I made this choice because the first man stole $ 3 billion and was sentenced for 40 months in jail. And, the other guy stole a hundred dollar bill because he was very hungry and needed somewhere to stay. The next day, he felt guilty and surrendered himself. He was sentenced for 15 years in prison.

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

If I was the judge I would charge the guy that took $3 Billion, 15 years to jail. I would let the homeless man go and give him $100 so he could have somewhere to stay and eat.
