### Sarissa's Proportion Post

Ratio- a comparison of two quantities that have the same unit measure. Rate- a comparison of two quantities measured in different units. Proportion- an equation which states that two ratios are equal.

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

5/360 = 1/72

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.

25 ml x4= 100ml
50 x 4= 200

3.3/4 = 12/16 or 4/9 = 16/32

Horizontal, vertical, diagonal.
The first one is correct.

4.

5.
I do not think this is fair.

If I where the judge I would have put Roy in jail for a less amount of time.
And I would have put Paul in jail for more time.

### Ayra's Proportion Post

Ratio: A ratio is a comparison of two quantities measured in the same unit

Example: you have a bag of 44 jellybeans, you pour 20 in your hand . It would look like this
44/20 or 44:20

Rate - A rate is two quantities measured in different units.

Example: The rate is when you read 40 words per minute.

Another example:

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

Example:

1. 1.5 hours to travel 360 miles is about 72 mph. 5/360=1/72

2. As a playground worker, if I increase the amount of apple jucie I am serving at the playground from 25 ml to 100 ml how much should I increase the orange juice to keep the quantities in the same proportion?

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

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

3/4 = 12/16 is true.

Diagonal:

Horizontal:

Q: Does it seem fair?

A: No it dosen't seem fair.

Q: With what you know about proportions look and read this image above does it seem fair? Why have you made this choice?

A: No it dosen't seem fair because Paul Allen stole \$3 billion dollars and went to jail for 40 months. While Roy Brown stole \$ 100 dollars and turned him self in because he felt guilty, but got sent to jail for 15 years.

Q: What would you have done if you were the judge?

A: If I was the judge I would give Paul Allen 15 years in jail, and Roy Brown 1 month in jail.

A ratio is a comparison of two quantities that have the same unit of measure.

Example:

A rate is a comparison of two quantities measured in different units. Example: \$1.69 per 100 grams or \$1.69/100g is a rate for purchasing bulk food. 72 beats per minute or 72 beats/min is a heart rate.

A proportion is an equation which states that two ratios are equal.

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

5/360 = 1/72

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

3/4 = 12/16 is true.

Diagonal:

Horizontal:

1. Does this seem fair?

- No it does not.

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 Paul Allen stole 3 billion dollars and got sentenced 40 months, while Roy Brown stole 100 dollars and got sentenced 15 years. Also, Roy turned himself in because he felt guilty.

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

- If I were the judge, I would give Paul a 15 year sentence and Roy a couple of months.

Ratio- A ratio is a comparison of quantities that have the same units. These are some ways of writing them.
Words: one compared to two or 1 to 2
Ratio Notation: 1:2
Fraction: 1/2

Rate- A rate is a comparison of two quantities measured in different units. It can be expressed as a fraction, but cannot be expressed as a percent.

Ex: 5 apples/hour

Proportion- A proportion states that two ratios are equal.

Ex: 2/4 = 3/6

• 5 hours to travel 360 miles is about _____mph.

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

1. No
2. No, it's not fair because he only stole \$100 and he surrendered to the police. While the EX-Mortgage CEO stole \$3 billion and he only gets 40 months in jail.
3. If I was the judge, I would send the CEO 180 months in jail and the poor man 2 years in jail.

no do not think this is fair because the homeless got 15 years of prison and only stole \$100 and then he felt guilty so he confessed . The other man stole 3 billion but only got 3 years in prison.
I really don't think this is fair

### Sarah's Proportion Post

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

Suppose that you have a bag of 20 marbles. You pour 5 marbles into your hand. The ratio of marbles in your hand to the total number of marbles is 5 to 20, or 5:20, or 5/20.

Rate - A comparison of two quantities that have different units of measure.

The rate at which you type may be 50 words per minute. The rate at which your parents' car travels may be 55 miles per hour.

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

Proportions can be used to predict information, such as: "a baseball player has a batting average of 50 hits in 100 at-bats. How many hits will she have in at-bats?"

1) 5 hours to travel 360 miles is about _____mph.
• 5 hours to travel 360 miles is about 72 miles 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.
• apple/orange 25/100 = 50/200

1) No this does not seem fair.

2) This is not fair because Roy Brown, just stole 1 100 dollar bill, and then turns himself in because he felt guilty, and he gets 15 years in jail!? And a banker steals 3 billion dollars (3,000,000,000) and he gets a 40 month sentence ( 3 years and 4 months) I don't think this is fair at all!

3) If I were the judge I would sentence The Banker to 15 years of jail, and i would sentence Roy Brown 1 month of jail.

1. There is a party in our neighbor he is serving 10 muffins and 5 glasses of chocolate milk in that serving 5 people can eat that. If there are 15 people in the party how many many servings of muffins and milk does he needed.

-muffins/chocolate milk 10/5 = 30/15

3/9 = 12/36 is true because 3 is divisible by 9 and 9 is divisible by 36.

4/8 = 9/17 is wrong because 4 is not divisible by 9 and 8 is not divisible by 17.

### Jackie's Proportion Post

1) What is the definition of ratio, rate and proportion?

Ratio: A ratio is a
comparison of two quantities that have the same unit of measure.
Rate: A rate is a comparison of quantities measured in different units.
Proportion: A proportion is an equation which states that two ratios are equal. *A proportion has 2 equivalent fractions. ( ratios)*

Here is an example of all these.

Rate And Proportion:The red shows how they are equivalent which proves how this is a proportion statement.
The words on the side show the word ratio.
The blue is the rate of how much shirts I would get for 2 dollars. The whole statement is the proportion statement.

Ratio: This shows 3 starfishes to 4 pearls.
There are many ways to show this.
Like part to part ratios. 3:4, 4:3, or in words starfishes:pearls, pearls:starfishes.
Another one is part to whole or whole to part ratios.
3:7, 4:7. 7:3, 7:4.
Part to whole and whole to part ratios are when you compare the whole to a piece.

2)5 hours to travel 360 miles is about _____mph or miles per hour.

Sentence: 5 hours to travel 360 miles is about 72 mph.

72miles/h

In order to get this answer, First I found the word ratios which were hours and miles. Secondly I put down the math information that fits into the problem into the right spaces, which were 5 hours so it goes beside hours and 360 miles beside miles. The 1 is what we are trying to find, which is how many miles per hour. Next I tried to find any relationships with the numbers and what i saw was 5 to 1, so 5 divided by 5 gets to one. So what you do to the top you do to the bottom. 360 divided by 5 = 72 miles which get your answer!

Question 2 B) 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.

Sentence: He should increase the orange juice to 250 ml.

The way I got my answer to this question is actually the same concept of what I did in the first question just with different numbers and on my first explanation in the picture above. It is pretty much the same thing just that I saw an easier relationship between 20 and 100 rather than 20 and 50. It isn't wrong if you do it the other way it just takes longer to find the relationship between harder numbers.

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 I can prove that equivalent ratios statements are true is by using diagonal by multiplying the number diagonal of them and both of the answers are the same.Another way is using horizontal multiplying. If the relationships horizontally on the bottom and top are the same and can get to the number placed there its equvalent. Lastly using the verticle way. The verticale way is the same concept just that you have to see the relationship at an up and down angle.

Just for note the 1.3 is repeated. Since the 1.3 repeated times the 3 does not equal 4, it is because 4 divided by 3 ends up with a repeating decimal but if you multiply it by three it ends up to be very close to 4. It is because the relationship between 3 and 4 is very hard to work with in relationships. Like having to work with 2 and 4 it is very easy because you get to use whole numbers and no repeats.

So this ratio statement is true.

This is a picture of the second ratio statement.
As you can see in all three ways they had to multiply by something else to get the the number that I needed to get to, to prove if the statement is true. But in this one it isn't because the results have to be multiplied by the same number for which ever way you chose just like the first statement above.

So this ratio statement is false.

Answer: So my answer is that the first ratio statement is the equivalent and true statement.

Here are some videos on proportions and ratios.

1) Does this seem fair?
I don't think this is fair at any circumstance.

2)With what you know about proportion look and read what is the image above. Does it seem just fair? Why have you made this choice.

This is my answer because 10 is a number that can fit into both 180 and 40. You might be wondering where I got 180 from. I got 180 months because there is 12 months in a year, and Roy was put in jail for 15 years so I multiplied 12 by 15 and got 180.
My proportion statement shows that if Roy stole \$12.50 dollars he would go to jail for 10 months?!?!?! That's just plain CRAZY! Especially if Paul stole \$750,000,000 dollars he would go to jail for 10 months. Plus Paul stole money even though he had a great job, while he didn't think of what he already had, so right now he just turned his life around. Unlike Roy he stole for a particular reason, it was to survive, and to pay to stay where he lives, and facing the fact he turned himself in from feeling guilty. This is clearly not a fair statement that happened.

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

What i would of done if I were the judge is that I would put Paul in for jail for the 15 years while Roy would be in jail for about a month, or month in a half.

Thank you for taking your time to read this!~ Hope this Helped You !~ (:
