Suzzene's Proportion Post

Task 1:

Please define-

Ratio- The comparison of two numbers.
Example: 1:4

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

Example: $0.85/orange

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

Example: 1/2= 5/10

Task 2:

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

x= 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.

x= 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

Task 4:


Task 5:

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?
It is not fair at all because a rich person who scammed 3 billion dollars out of people only need to serve in jail for 3.5 years while a guy who desperately needed money for food and such stole only $100 and yet, needs to serve for 15 years.

4.What would you have done if you were the judge?
I would've given the homeless man food and maybe around 3 months of community service and 15 years for the man who had scammed people out of 3 billion dollars.

Sydney's Mazur's: The Grand Proportion Post

Ratio - the relationship between 2 numbers like 4 and 6 have the number 2 in common

Rate - a kind of ratio that compares 2 different types of numbers like 400, and 11, and all that kind of thing

Proportion - relation between things or parts of things like pies and almonds

It was not fair because the poor chum didn't actually hurt anybody (it said `threatened`, not hurt), took only $100, and he felt guilty (meaning he had a conscience) and then gave the money back. If I were the judge, he would get 3-6 weeks of community service.

And for the other feller, he took wayy more money. He should be locked up in jail for years and more years.

The homeless guy is actually the chap, and the other guy is the chum.

And the rest of the instructions I forgot the meaning of (so please don`t get too mad at me).

Aicelle's Proportion Post

What is ratio?

A ratio shows the relationship between 2 quantities.
Ex. 13:43

What is rate?

A rate compares two quantities measured in different units.
Ex. 40m/h or $0.70/100g

What is proportion?

A proportion shows an equation which state that 2 ratios or fractions are equal.
Ex. 4/8=48/96

4x12=48 8x12=96

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

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 orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with. 200 ml

25/100 = 50/x

25x4=100 50x4=200

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

3/4 = 12/16 TRUE

4/9 = 16/32 FALSE

Proportion problem image

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? No, it does not seem fair because the homeless person had 15 years in prison for stealing $100 to have a place to sleep in, but surrendered the next day because he felt guilty. While the CEO of the Ex-Mortgage took away $3 billion and only went to prison for 3 years.
   
3. What would you have done if you were the judge? I would have given him a year or 10 months in prison because he surrendered voluntarily also he only took $100. The CEO, I would've given him 30 years in prison because he took away the $3 billion from the company.
   

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

example: A ratio is a comparison of two numbers. Separate the two numbers in the ratio with a colon. you want to write the ratio of 3 and 12.We can write this as 3:12 or as a fraction 3/12, and we say the ratio is three to twelve.

Rate : A measure, quantity, or frequency,one measured against some other quantity or measure.

example: You have a family of four people; 2 adults, one 9 year old child, and one 5 year old child. You have selected the American Plan Package (basic cabin rate + 3 meals per day) as the best package for your family. You would like cabin #33. Your rate would be $380.

Proportion: A part or number considered in comparative relation to a whole.

example: Solve for n: 1/2 = n/4. Using cross products we see that 2 × n = 1 × 4 =4, so 2 × n = 4. Dividing both sides by 2, n = 4 ÷ 2 so that n = 2.

5 hours to travel 360 miles is about _____mph

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?

No it doesnt seem fair because the homeless guy only took 100$ and he didnt hurt anyone.

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

if i were the judge i would have let the homeless guy go.

Liyanah's Proportion Post

Task 1
Definitions:

Ratio: A comparison of quantities that have the same units.
example: 3:9, 9:3

This picture shows 3 squares and 6 circles, if you wanted to make a part-to-whole ratio you would use 3(squares):9(whole)= 3:9.







Rate: A comparison of two quantities measured in different units. example: $1.69/100g, 72 beats/m.










Proportion: An equation which states that two ratios are equal.
example:










Task 2

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

Task 5
http://www.concurringopinions.com/wp-content/uploads/2011/10/CrimeInAmerica2.jpg

1. No, i do not think this seems fair.

2. I dont think this is fair because the homeless guy only stole $1oo and he was sent to jail for 15 years. The rich guy stole 3 million dollars and only got sent to jail for 40 months. I dont find that fair because the homeless guy ONLY stole $100 and he was also being honest that he stole it and returned it. The rich guy wasnt, and he spends less time in jail. That is really unfair.

3. What i would've done if i were judge was put the rich guy in jail for 10 years and put the homeless guy for 2 months only because i like how he was honest about stealing $100 and returned it.

I hope you all like my blog!

Michael's Propotion Post

Ratio- The relation between two similar numbers (1:2)
Rate- A comparison of two quantities measured in different units. $1.69 per 100 grams or $1.69/100 g is a rate for purchasing bulk food. 72 beats per minute or 72 beats/min is a heart rate.
Proportion- An equation which states that two ratios (fractions) are equal.

Task 2
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. You can just x2

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 Three ways you can prove it is equivalent is cross multiply , horizontal, vertical, and diagonal.

4/9 = 16/32 is FALSE because what you do to the top and the bottom the answer is different.

1.Does this seem fair? This does not seem fair because the homeless guy only stole $100 and was sent to jail for 15 years. The rich guy stole 3million dollars and he got sent to jail for 40 months. The rich guy stole more but went to jail for less time then the homeless guy. This is not even close to being 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? It does not seem fair because the rich guy stole more money but went to jail for less time then the homeless guy. I've mad this choice because the judge is dumb for putting someone to jail that stole $100 and get put in jail for 15 years.

3. What would you have done if you were the judge? If i was the judge i would of put the rich guy in jail for 30 years and the homeless guy for 10 months.

5.Does this seem fair? Well to me this isn't fair because the homeless guy only stole 100$ and got sent to jail for 15 years and the rich guy stole $3 billion and got sent to jail for only 40 months.

This isn't fair because the rich guy stole a lot more money than the homeless guy did and the rich guy only got sent to jail for 40 months. The homeless guy only stole $100 and got sent to jail for 15 years. It should be the other way around. The homeless guy should of been sent to jail only for 40 months and the rich guy should of been sent to jail for 15 years.

If I were the judge I would send the homeless guy to jail for only a year for confessing and send the rich guy to jail for 20 years.
