Samantha's Proportion Post

Task One

Ratio- shows the comparison of two or more value that has the same units

The image beside shows an example of a ratio, it can be shown three ways:

3/4, 3:4, three compared to four

Rate- a comparison of two quantities in different units

For example 3 apples cost $1.50, how much would 1 cost?

The answer would be $0.50, the rate would be 1/$0.50

Proportion- an equation which states that two ratios are equal

An example would be, Trevor runs 25km in 10 minutes, how long would it take for 100km?

Task Two

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

hours 5 (÷5) 1

miles 360 (÷5) 72

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.

apple juice 25ml (x4) 100ml The worker needs to increase 50ml to 200ml.

orange juice 50ml (x4) 200ml

Task Three

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

3/4 = 12/16 The first way is horizontal, the next is crisscross and last is vertical.

Task Four

Task Five

1)Do you think this is fair?

No, this doesn't see 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?

I don't think this is fair because if you were to compare the amount of money in a proportion statement, the CEO has technically stole way more. Since the amount stolen by the CEO is very high, his jail time should be high as well, but this man didn't steal as much but he got put in jail for an unreasonable amount of time. Just because this man was homeless and a different race does not mean he should get a longer amount of time in jail, it should matter on how much they stole!

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

If I were to be the judge of this case, I would have sentenced the opposite way or maybe even worst for the CEO. The man in the image should have only gotten the 40 months in jail and the CEO should have gotten the 15 years in jail.

Peter's Proportion Post

Task 1
Ratio- (part to part) compares different parts of group to each other.

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


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

Example: If 2 oranges cost $0.50 how much would 6 oranges cost?



Task 2

1. 5 hours to travel 360 miles is about 72 mph.
2. A a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, hoe much should I increase the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with.

   1. Does it seem fair? No, I don't think it's fair.
   
   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 this is not fair because the CEO took $3 billion and only in prison for 40 months which is 3 years and 4 months, and the homeless person took only $100 and get a 15 year sentence.
   
   3. What would you have done if you were the judge?
   
   I would sentence more than 15 years and the homeless man for about 2 weeks
   

Marlo's Proportion Post

Proportion: An Equation which states that that two ratios (Fractions) are equal.

Word
------ ------- = ------
Ratio

Ex. 172cm= 1 square there are 80 squares

Ratio: A ratio is a proportion that represents that relationship between two different things.

Rate: A comparison of two quantities measured in different units

Example of a rate is 64 beats/minute

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

Its 72 miles per hour or 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.

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

3/4 = 12/16 or 4/9 = 16/32

4/9 and 16/32 arent equal.

Heres a video about proportion:

Does this seem fare? No I dont think its fair.

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 its not fair because if you try to do the math and change the 100 to 3 billion and change the years to make it the same as the old CEO he would end up way longer than him he would end up in jail for more than 45 billion years. while the old CEO only has to do 4 years.

What would you have done if you were the judge?

If I was the judge I would of probably been more fair to him and I would of only let him stay there for like 3 months I know its not really the best choice in his case but Im just trying to be realistic.

Cyerra's Proportion Post

Task 1

Ratio - shows the relative sizes of two or more values

Rate - compares 2 quantities measured in different units.

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

--------------------------------

Task 2

5 hours to travel 360 miles is about 72 mph

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.

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

Multiples of 3 - 3, 6, 9, 12

Multiples of 4 - 4, 8, 12, 16

3 divided by 4 = 12

4 divided by 4 = 16

******* 12/16 ********

Task 4

Task 5

1) Does this seem fair?
- No, it does not seem fair.

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?
- The image above is not fair because the man gets 15 years in prison for stealing $100 and the other gets less than him besides the fact that his case involved a lot more money.

3) What would you have done if you were the judge?
- If I was the judge, I would give the other man a lot more time in prison due to the fact that his case involved more money and his case sounds more serious than the man who stold the $100.

Joy's Proportion Post

Ratio: A relationship between two numbers of the same kind.


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

Ex.

Car drives 3 hours and goes 300km. How far does it go in 1 hour ?

Proportion: An equation which states that two ratios (fractions) are equal.


1. 5 hours to travel 360 miles is about _____ mph

Answer: 72 miles


2. As a playground 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.

1. Does this seem fair?

-No it isn't

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 because the guy steal $3 billion and he only has to do 40- month sentence and the other guys stole $100 dollars and goes to jail for 15 years. So it doesn't really make since he took 100 and his going to spend 15 years in jail but the other guy stole 3 billion and just have to do 40 month sentence so it doesn't really make sense .

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

- If I were the judge I would do it another way like the guy who stole the 3 billion goes to jail for 15 years and the other guy who stole 100 dollars would do 40- month sentence.

Task 1
Proportion-An equation which states that two ratios are equal.

Ratio- A comparison of two quantities that have the same unit of measure.

Rate- A comparison of two quantities measured in different units

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. It would be 200ml.

Task 3

What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16

1) multiply top left to bottom right
multiply bottom left to top right

2) divide top left by bottom left

divide top right by bottom right

3) times top left with a number to make top right

times bottom left with a number to make bottom right

Task 4

Task 5

1) Does this seem fair?

No it doesn't seem fair.

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 still doesn't still seem fair. For someone to steal $3 000 000 000 and get prison for 3.5 years is ridiculous, also for someone to steal $100 and go to prison for 15 years is more ridiculous. Most Unfair Thing To Do!!!

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

If I was judge I would give him about a week of Community service.

or

I would let him in jail for 1 month.
