Stephanie's Percentage Growing Post

Question 1;What is a good definition of percent? You should use words symbols pictures and numerical examples in your definition.

It is an equivalent fraction out of 100 you will know it is a percent because you'll see this sign after the number %


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.


They are all equivalents.
Because 3:2 , you add the two numbers together and you get 5 and that is the denominator and the first number of the ratio is the numerator so it's 3.
Then i would be 3/5.So both are the same value.
Now 60% is the same to all of these because to find a percent you have to divide numberator(3) by the denomenator (5) then you multiply it by 100 and you get 60% (n/d*100=%).
So that means it is similar because 3/5 = 0.6 * 100 = 60%.


Question 3;

Show 3 different ways to fine 35% of 80.There are 100 squares in each:100 divided by it gives you 1%. So its 80 divided by 100 which equals 0.80.8 is how much one area of a square equals.






4;Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review.I left a comment on this person’s blog.http://linden8z.blogspot.com/2006/12/review-of-percent.html




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: 40/2=20

Ms. Lowrey: 40/1.5=26.66

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?


I did it On PAPER =P

Question # 1

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



A percent is a number that you get out of a whole by dividing by 100. Example, if you got 18 out of 20 on a test that be 90% by dividing 18 by 20 you would get 90

Question # 2

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



Decimal

0.6 = 0.6 * 100 = 60%

60/100 = 3/5

100 – 60 = 60:40 or 3:2

Ratio


3:2 = N-N = 3/5

3/5 3/5 = 0.6

3/5 * 100 = 60%


percent




60% = say it, write it, 60/100 or 3/5

60 /100 = 0.6

100 – 60 = 60:40 or 3:2

fraction


3/5 = 3/5 * 100 = 60%

3/5 = 0.6

3 – 5 = 3:2

Question # 3

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

frist way

80/100 = 0.8

0.8 = 1%

35 * 0.8 = 28

second way
80 / 10 = 8
8 = 10%
8 + 8+ 8+4 =28
10 + 10 +10 +5 = 35
28 = 35%

third way

80/2 = 40

40 = 50%

40 /2 = 20

20 =25%

0.1/80 =8

8=10%


Question # 4

Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (what the post was talking about …yes you have to read the post and why others should read the post) hint in side the side bar there are link to other schools. Three of them done work on percentages!

8M Math: Understanding 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 can be correct because she may have more student then Ms Lowrey has.

lets say Ms Stanzi class has 30 students in her class and Ms Lowrey has has 20 in her class.

15/30 is 50% and 11/20 = 55%

Question # 6

Use a hundred grids (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 /40 * 100 =40%
B) What is 120% of 30?
120% of 100 is 120120/100=1.230 x 1.2=36120/100 = 36/30

Lisa s growing post =)
I don't now how to add pictures yet.
1.what is a good definition of a %?You should use words symbols. Pictures and numerical examples in your definition.
My answer:
A Percent is a number out of 100. EXAMPLE=20% is 20/100
1.How are three fith's (3/5), 3:2, 60% and 0.6all the same ?n Use a picture and words to show your answer.
My answer:
1/5=20% 1/5x3=60% 10=60 3:2 =part/part+whole= fraction 1/5=20% 1/5x3=60%
3.Show 3 different ways to find 35%of 80.
My answer:
first we have to find what what 1% =80divided by 100 =8 so 1 = 8. (1%)x 35 =28 so 35% of 80 is 28.
4. Find a Link that deals with percentages. Leave a comment behind and add the link with a review.
My Answer:
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.
My Answer:
Ms.Stanzi is corret because there can be more children in M. Lowerys Class.
My work:
20/40=50% 11/20=55%
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?
My Answer:
A. 40%of 100 is 40
40/100=0.4
16x0.4=40
40/100=16/40
I got this answer by dividing 40 by 100 that gives me 0.4, and then you multiply the decimal by the part that gives you 40% of 16.
B. 120% of 100 is 120120/100=1.230 x 1.2=36120/100 = 36/30
I got this answer by finding out what 120%of 100 is and it is 100, and then I divided 120by 100which gives me 1.2.Then you multiply by the whole which is 30 by 1.2 and that gives you 30 out of 36
