Charisse's proportion post

Task 1
Please define
  • ratio
  • rate
  • proportion
Ratio- The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

example of a ratio-

This picture represents 6 stars, 4 green dots, and 5 red dots. If you were to compare the 6 stars to the whole, in ratio form you would put 6:15 because there is 15 all together.

Rate- comparison of two quantities measured in different units.

Proportion- An equation which states that two ratios are equal.

horizontally 2x2=4, 8x2=16. Vertically 3x3=9, 12x3=36. Statements are equal.

Task 2
Copy these questions into your post. Answer them using proportion statements.
  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. 200 ml!

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

The three ways you can prove that the equivalent ratio statements are true is multiplying horizontally,vertically, and diagonally. If the number multiplies in the number for each side, then the statement is true.

I chose to do horizontally for 3/4=12/16

For 4/9=16/32 I chose to do it vertically.

Task 4
Find a video about using proportion and embed it in your post. Make sure you select the small size of the video.

Task 5
We are starting to engage in discussions about social justice. What do you think about this image below. Use the link to copy it into your post. Then answer the questions

  1. Does this seem fair? I do not think this is fair because the homeless man stole only $100 but turned himself in the next day because his mother didn't raise him that way but got sentenced to 15 years in prison. Paul R Allen who did a scheme by possibly stealing 3 billion dollars from mortgage lenders and got only 3 years in prison. This absolutely doesn't make any sense because the homeless man only stole $100 with 15 years in prison and a scheme holding 3 billion dollars for only 3 years in prison. This should be the opposite as what I think. I also think that the judge might possibly be racist.
  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?
By looking at the proportion that I made and reading what's in the image above, it is not fair. I've made this choice because $3 billion is way bigger then just a $100 bill. At least the homeless man was brave enough to turn himself in after one day and Paul got caught while frauding. I just think the judge is being racist.

3. What would you have done if you were the judge? If I were the judge, I would respect the homeless man because he was honest and he knew what he did was wrong. I wouldn't give the homeless man 15 years in prison for just a $100 bill that he turned in the other day, it would be stupid. I would've probably gave him at least 3 months in prison because he should have known the first place that stealing is wrong. For Paul, I would not give him 3 years in prison, I would give him 10 years because he was basically stealing money which was 3 billion dollars and wasn't his. He wasn't honest like the homeless man and he probably didn't feel bad about it.
