Melissa's Growing post

Okie...Here's my growing post
Question 1: What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.

-A percent, to me, is the overall number out of 100. It is expressed as this symbol:%. It supposedly came from the term "cent" which means "100" in French. And since a percentage meant something out of 100, we call it "per" "cent". Some percentages are: 50% (1/2 or half), 25% (1/4 or quarter), and 10% (1/10)...or dime...Haha I'm just kidding.

Here is
my percentage web. I included most of what I've already said above, and used gliffy. I'm not a total expert at using it yet so it's not perfect. Hopefully it's understandable.













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.

-These all equal the same thing. The only difference is tha
t they're written in different equivalents. Don't get confused. Let me explain...

-
This column shows the different equivalents.

-These are the equivalents for 3/5.

-These are the equivalents for 3:2.


-These are the equivalents for 60%.

-These are the equivalents for 0.60.




No matter how different you write them, they'll always equal the same thing.


Question 3:
Show 3 different ways to find 35% of 80.

-Okay, here's my grid that shows 35% percent out of 80.

1. The first way I came up with is to figure out 1%. It's probably the easiest way for finding the answer, and it's always correct. 80/100 (/=divide. I don't think the computer has a dividing sign) =0.8.
0.8x35=28. 28=35% of 80.


2. Here's the second way. 80/10=8

8/2=4(5%)
8x3=24+5%(4)=28


3. Here's my third way. 80/10=8
8/2=4(5%)
4x7=28

Question 4:
Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review


-Okay. here are some the one I've found...

-http://linden8am.blogspot.com/ - this class is learning how to convert decimals, fractions, and percentages. I left a comment for one of the students saying that their scribe was very well done and that it was easy to read and was understandable because of the diagrams.


Question 5: The principal announced that 50% of the chi
ldren 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.

-I think that Ms. Stanzi isn't correct; unl
ess she has more students. See, if Ms. Stanzi claims to have the greater amount of accomplishment, that must mean that she has more students.



















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?



To find out what the number is, I divided 40% by 40%. 16/40=0.4.
The next thing I did was multiply 1% (0.4) by 100. 0.4x100=40.

40/100=16/40

If you divide 40 by 100, and 16 by 40, you should get the same answer. If you do, then you know that you did this correctly. 40/100=0.4 16/40=0.4




b) What is 120% of 30?

For this question, you could instantly tell that the answer is going to be over 100%.


To find the answer, first you'll have to know that the fraction of this question is 120/100. Knowing that, you'll have to find out the extra 20%.
This is what I did: 30=100%
To find 20%, 30/10=3x2=6
6=20%
The rest is pretty straight forward: 100%+20%=120%.
30+6=36.
36=120%.

Man...I thought I'd never have this done...XD
