This post talks about percentages. Per means 'part' and cent means 'for every hundred'. Percentages are a lot like ratios because they are both comparing multiple numbers.
A percentage formula would look like this:
Numerator divided by denominator=decimal multiplied by 100=_%
Others should read this post because it can help them if they don't understand percentages.

Question 5
The principal announced that 50% of the children in Ms.Stanzi's class met their reading goal for the month and that 55% of the children in Ms.Lowrey's class met their reading goal for the month. Ms.Stanzi said that a greater number of her students met their reading goal. Could Ms. Stanzi be correct? Why or Why not.

Ms.Stanzi could be correct because 50% of any number is always half and 55% of any number is more than half. Ms.Stanzi could be wrong because it doesn't matter what number or how big that number is.

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?

16 is 40% of 40

b) What is 120% of 30?

120% of 30
120 divided by 100=1.2
1.2 multiplied by 30=36
120% of 30=36

I Marked and Commented On:
Julie Rose 8-16 I gave it a 60 out of 65.
Marielle 8-17 I gave it a 60 out of 65.
Nick 8-16 I gave it 19 out of 65.

Question 1
What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition. (suggestion gliffy is an excellent tool for adding detail to your definition.)

- a percent is a number out of 100. it is also called "per centum".
the term per means "by the hundred" and the term cent means 100.

Question 2
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

- 3/5 = 3 divide by 5 = 0.6 x 100 = 60%
- 3:2 = 3/5 = 3 divide by 5 = 0.6 x 100 = 60%
- 60% = 60%
- 0.6 x 100 = 60%

as you can see.. they all have the same value.

Question 3
Show 3 different ways to find 35% of 80. (bubbleshare is an excellent tool to animate the many different ways of finding these answer).

- 100 divided by 100 = 1%
80 divided by 100 = 0.8
0.8 x 35 = 28

- 80 divided by 2 = 40 = 50 %
40 divided by 2 = 4 = 5 %
40 - 4 - 4 - 4 = 28
50% - 5% - 5% - 5% = 35%

- 28/50 = 35/100
35 divided by a 100 = 0.35
0.35 x 80 = 28%

Question 4

Ms. Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

20 divided by 40=50% 11 divided by 20=55% Ms. Stanzi is right because theres more kids in Ms. Lowrey's class.

Question 6

Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

16 is 40% of what number?
- 16 divided by 40= 0.4 x 100 = 40

What is 120% of 30?
- 30 divided by 120 = 0.25 x 100 = 25

Question 1
What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition. (suggestion gliffy is an excellent tool for adding detail to your definition.)






Examples
1.)1/2 = 1 divided by 2 = 0.5 x 100 = 50%
2.)1/4 = 1 divided by 4 = 0.25 x 100 = 25%
3.)3/4 = 3 divided by 4 = 0.75 x 100 = 75%
4.)5/35 = 5 divided by 35 = 0.142 x 100 = 14.2%


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

other way you can show percents: ^^ im still gonna use the numbers from my example

1.) 1/2 is the same as 50/100
2.)1/4 is the same as 25/100
3.)3/4 is the same as 75/100
4.)5/35 is the same as 14.2/100

**how would you know if it's the same?!?!... you would know it because if you divide both the numerator and the denominator together you get the same answer **

for example:

•8/36 = 8 divided by 36 = 0.222 x 100 = 22.2%
•22.2/100 = 22.2 divided by 100 = 0.222
8 __ 22.2
-- = ---- = 0.222
36 _ 100

Question 2
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

•3/5 = 3 divided by 5 = 0.6 x 100 = 60%
•3:2 = 3/5 = 3 divided by 5 = 0.6 x 100 = 60%
•60% = 60%
•0.6 x 100 = 60%

** If you convert them all into percent you get 60%. That is how they're all the same**

Question 3
Show 3 different ways to find 35% of 80. (bubbleshare is an excellent tool to animate the many different ways of finding these answer).

1 way:

•100 divided by 100 = 1
•80 divided by 100 = 0.8
•0.8 = 1%
•0.8 x 35 = 28%

2nd way:

•28/80 = 35/100
-------------------------
•28 divided by 80 = 0.35
•35 divided by 100 = 0.35

3rd way:

•28/50 = 35/100
•35 divided by a 100 = 0.35
•0.35 x 80 = 28%

Question 5

The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

••••Ms. Stanzi could be correct. If she had a class of 45 and 50% of her students met the reading goal then she is right because if Ms. Lowery had a class of 30 and 55% of her class met the reading goal Ms. Stanzi's class achieved the goal because even though Ms. Lowery's class had a higher percent (55%) Ms. Stanzi has more kids than her.••••
------------------------------
Ms. Stanzi
------------------------------
•100 divided by 100 = 1
•45 divided by 100 = 0.45
•0.45 = 1%
•0.45 x 50 = 22.5
•22.5/45 = 50/100
------------------------------
Ms. Lowery
------------------------------
•100 divided by 100 = 1
•30 divided by 100 = 0.3
•0.3 x 55 = 16.5
•16.5/30 = 55/100
------------------------------
••••Ms. Stanzi could also be wrong if Ms. Lowery had a greater number of students in her class than Ms. Stanzi••••
------------------------------
for example.....
------------------------------
Ms. Stanzi had 40 students and Ms Lowery had 30.
------------------------------
Ms. Stanzi
•••• •••• ••••
1) 40=100
2) 40/2=20
3) 20=50%
•••• •••• ••••
Ms. Lowery
•••• •••• ••••
1) 30=100
2) 30/2 =15
3) 30/2.5=12
4) 20+12=32

A percentage is an equivalent fraction that is out of 100. Percentages can be converted into decimals, ratios, and fractions. And so on... Here is a web that shows you what you can do with a percentage. Click here.

I chose the first post because it was talking about percentages. He explained how to get a percent very good. Also he said, why should other people read the post, and I think it could help other people like me.

Question 5
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms. Stanzi could be right if she has more children in her class.

Example:

Ms. Stanzi has 36 kids in her class and Ms. Lowrey has 30 kids in her class. Ms. Stanzi's class has 18 kids that met their reading goal. (36 ÷ 2=18)
While Ms. Lowrey's class only had 16 or 17 kids that met their goal . (30÷100=0.3, 0.3x55=16.5)

Therefore, Ms. Stanzi is not correct.

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?

b) What is 120% of 30?

30 ÷ 100 = 0.3

0.3 x 120 = 36

120 % of 30 is 36.
