Journal Entry 10/11/10
Today in class we learned about percents or per cents, decimals, fractions and how to work with them. We were taught how to make fractions decimal or percents decimals, and finding percents of different numbers, like what percent of 40 is 15? and you would end up as 37.5% for your final answer. Also, the word percent means divided by 100!

@Diana, only on some. You are welcome April!

Journal Entry: 10/11/10

Today in Mr. Gerson's 4th period class we learned ways to convert decimals, fractions, and percentages. You can do it in the proportion way or division way. He also taught us how to find a missing percent or number, using rations. Example: What percent of 20 is 18? If you use the proportion way, the equation is n/100=18/20. If you use the division way, the equation will be different. so n=90%.
Per/cent
division/out of one hundred
percent=to divide by one-hundred

Eric for the chapter 3 wrap up do we have to justify it all?

Kiana M. Period 4 said...

For the study guide, do w have to show our work on a seperate sheet of paper? or do we do what we always do and just answer the question? Help please:)

MatteoMTAPer.4 said...

what about the wrap up?

DavidR Per.3 said...

Journal Entry 10/11/10
Today in class we learned about percents and fraction. Also I learned that per cent used to be two different words and later changed to one word and means divide by 100.We learned how work out problems like change 48% in to a decimal which turned out to be .48.

Kiana M. Period 4 said...

Huh? i just wanna know about the study guide...

MatteoMTAPer.4 said...

what about the wrap up?

KathyS. Per.2 said...

@Matteo, I answered your question earlier. @Kiana, Sorry I don't know!

MatteoMTAPer.4 said...

when

Kiana M. Period 4 said...

@ Kathy
What do u mean by only on some?

Unknown said...

kiana, for the study guide you can do the work on the paper or on a seperate sheet

Kiana M. Period 4 said...

Thanks Gabi but do you know what problems you have to do justifications for (on the wrap up)?

KathyS. Per.2 said...

@Kiana, that is what Mr. Gerson said in class.
so I do justifications on the first one in every lesson that needs justifications. Is that okay Mr. Gerson or do I need to do more than that?

Natasha L Per.4 TA said...

sorry typo

Period 2:
Period 3: David R.
Period 4: Paula H.
Period 5: Breana E.
Period 6:

well obviously you can't really justify .....
ex: convert 30% into a decimal* -->
30% -->30/100 -->0.3

Kiana M. Period 4 said...

Ohhhh! Thanks! That would really save me some time...

Kiana M. Period 4 said...

And Natasha, we're talking about the wrap up:)

Natasha L Per.4 TA said...

:) good luck! ps too whom this applies to: don't start the wrap at at 12:00 am today that would be a very badddd idea ;)

Kiana M. Period 4 said...

Thanks! I'm gonna need it;)...

i need help with number 20 on the study guide???

Sean K Per.3 TA said...

what is it?

David P period 4 said...

hey are we supposed to show our work for the study guide?

Sean K Per.3 TA said...

I don't think so, but I would highly recommend it.

Anonymous said...

Sean, you decide to market ur own custom computer software. you must invest $4212 on computer hardware, and spend $3.20 to buy and package each disk. if each program sells for $11.00, how many copies must u sell to break even?

SeanOPer.4 said...

we only need to show justification for like only 10 probs rit?

David P period 4 said...

@sean
thank you!! which means we dont have to justify it too right?

SeanOPer.4 said...

@david idk thats y i am asking other poeple =_=;;;

Unknown said...

do we have to wright down the questions on the wrap up?

AnalissaTPer.4 said...

do we have to do justifications for p.156???

MatteoMTAPer.4 said...

No we don't.

MatteoMTAPer.4 said...

Tom, yes

Anonymous said...

what are the pages for the wrap up thats due tomorrow?

MatteoMTAPer.4 said...

Pg 165- 168.

Sean K Per.3 TA said...

okay. so you start by investing $4212, so you are at -4212 now. making each disk costs $3.20, which is -3.20. Then you sell them for $11.00 or +11. So each disk makes a profit of 11 - 3.2, or $7.80. Then the variable is the amount of disks needed to break even. If each disk sells for $7.80, then you need to find out how many are needed to get to 4212.
equation: 7.80x=4212
solution: Figure it out yourself

Anonymous said...

wait so we do page 165 167 & 168?
or does it like end on page 168 so we only have to do 165 & 167?
or all three?

®¥Ώ Ⓣ. ℙĕ®. ④ said...

#9 find 3 consecutive integers with sum -387. which is the greatest of the 3?

Sean K Per.3 TA said...

@ryo
here is the way I do it. Since they are consecutive. you can do
first # x-1
second # x
third # x+1
-387/3= -129 x=-129
-129+1=-128

Journal Entry October 11,2010
Period 2
In class today we learned about percents. The word percent use to be two words per and cent; per meaning divide and cent meaning 100.
We also learned how to turn percents into decimals,for example:
48%=48/100=0.48
Explanation: First you must turn the percent into a fraction by simply putting 100 as the denominator. Then you move the decimal to the left two times.

How do you write the equation for problem #6 in the ch.3 wrap up? Please help:)

u like my new photo? this will happen when global warming finishes melting Antarctica. *the penguins will march and invade us!*

thanks sean
and willy, does that have anything in common with math?

Holden said...

Journal Entry 10/11/10
Today in class, we learned about percents. The method below is a lesson I learned in class about expressing fractions as a percent:
3/5 = n/100
5n = 100*3
5n = 300/5
n = 60%
I also learned that percent can be two words,per cent.

Willy Wang TA.4 said...

no. but do u think i should change it to a panda with a minigun?

Paula H said...

Willy, that has nothing to do with math

Unknown said...

Do we have to justify for the study guide? Some people say we do, but others say we don't.

YoonyJ.Per.6 said...

journal 10/11/10

Today, we learned about percent. Percent means divided by hundred. we also learned how to change percents to decimals and fractions. For example, 24/25= 0.96 and when you move two spaces to the right, it becomes 96%. So 24/25= 96%

Unknown said...

Today in Mr.Gersons period 5 we learned about Percents, Decimals with fractions and how to convert them. we learned how to change a decimal into percents and percents into decimals.

example 1.
a) 48% into a decimal
48%=48/100
=0.48

Do we need to do justifications for the chapter 3 wrap up ?

AyaB.per.6 said...

Journal Entry October 11, 2010

Today in class we all learned about Percents and what it means. Per-Cent, Per means to divide and cent means 100 so put that together and its dividing by 100. We learned how to convert fractions, decimals, and percents. There are two ways to solve the problem proportion or the division way.
Example:(percents to decimals)
10% move the decimal to the left.
= 0.10
easy as that.
Another Example:(fractions to decimals)
1/2
divide 1 by 2
= 0.50

Journal Entry 10/11/2010
Today in class we learned how to convert fractions in to decimals, decimals into percentages, and fractions to percentages.
For Example: 0.95
0.95= 95/100=95%
Another Example: 0.35
0.35= 35/100= 35%

You have to move the decimal to the left two times in these two examples.
