Renz Adame's Blog post






Hello everybody, this is Renz A. and this is the blogpost for Friday, December 4th, 2009.


Today we worked on our unfinished homework on Practice page 68 of the text book the whole class. We didn't do much and i cant really blog much about it except that i can put up pictures to show how to do some of the questions.



Some of the questions are:


Page 68:

#5. a)
(Click on the page to enlarge)















#6. a)
















#7. c)












These are just some of the questions from the homework and there is more but this is all for now.

The next scribe is..............................................................Giulio

Hey everyone.



Yesterday, no one post the scribe, so lets talked a little bit about that :).

  • So the things we did yesterday was to write the "Keyideas" on page 67 in our own words.
  • And we also answered the "Communicate the Ideas" on page 67 and 68.
Now, lets talked about the things we did today.

Sign(negative,positive) of Multiplying and Dividing
-When multiplying and dividing integers(negative and positive), if there is an odd number of negative signs then the answer will be negative.







And then we answered our homework...
Communicate the Ideas [pg. 67 and 68] Here are the answers:

1]

  • c.) The common denominator I prefer is 12 because its easier to simplify and because the "MATHEMATICIANS ARE LAZY!".
2]


3]






  • c.) A. Because its easier.
4]
  • Because sometimes you forget to put the sign after you solved it.

_______________________________________________________

9-06 Dont Forget to do our homework on the book.
Heres the online link for the ebook "CLICKY HERE!".
The homework is at "PRACTISE ON PAGE 68-69".

For the next scribe I pick.




hahah *peace*...

SORRY FOR ALL THE MISTAKES :)

Dont FORGET TO Drop some COMMENT[s].

Uhm Mr. B Sorry If i posted it late because I forgot that im doing the scribe *sorry*.

Today In Math Class We Learned , When Adding and subtracting fractions , To do so you have to find a common denominator If Necessary . Add And subtract Numerators denominators Have to be The Same The Simplify .

This Image Shows Adding Fractions . It Is also The same When You Subtract But The numerator numbers wil be subtrac
ted instead














We Also Learned In class how to Multipy Fractions .
When We Multiply Fractions , Simply multiply The Numerators Together and then multiply the Denominaters Together , Then Simplify If Possible :)









For HomeWork

We Had 10 questions to do :)

1 : 2/3 x 3/5 =
2 : 4/5 x 2/9 =
3 : 7/8 x 4/5 =
4 : 9/10 x 5/6 =
5 : 2/5 x 3/4 =
6 : 1/9 x 1/9 =
7 : -1/2 x 2/3 =
8 : -2/7 x 7/2 =
9 : -4/5 x -5/4 =
10: 6/7 x 1 1/6 =

And also Page 2.2 in Our math books :)
I choose Raye To do the next Scribe :)

Hey guys! (: On Friday in math class we learned about more fractions. We also went over the homework from Thursday.



Here's a question that some people had troubles with from the homework on Thursday:


















This is the exact same question just solved in a different way.

















Now here's a question Mr. Backé asked us to try in class on Friday:

*Mr Backé showed us 2 different ways to solve this.

Here's one way:























Here's a second way:




















HOMEWORK!



1) 2 7/8 - 1 1/4=





2) 3 5/6 - 2 2/3=





3) 11 3/4 - 2 7/8=





4) 5 1/2 - 5/6=





5) 3 1/8 - 1 1/6=




I pick Nicole N for the next scribe. =)

What's up guys! today we talked about fractions and as always we first clarified and corrected homework for today.
the number ten was the one that seemed more difficult, but here is the solution for you =)
:


First we need to find the denominator....and that is 60!
and as second we need to calculate the numerator and that will be:


77/60=17/60 and thats the answer!
anyway after that we did exercises on fractions like that:



and that:



.....that's it!
Hope that you understood how to proper fractions(in my first subscribe xP)!

thanks for
Jericho to choose me ;)
anyway don't forget to leave a comment and the homework for tomorrow!!
see ya!

Friday ,November 13
Today we went to the computer lab to learn more about fraction at nlvm.usu.edu
First got to Number and Operations (Grade 9-12)and then to Fractions-adding





This is somehow it is look like. What we need to do here is to find out the sum of the fractions shown. First you should rename the fractions 1/7 and 1/2 so their denominators would be the same.




Now the denominators are the same you can now add the fractions.

When adding fractions with different denominators you should rename it with its equivalent fraction to make the denominator the same.

After that we went to lumosity.com, created accounts then played some games about math.

After we leave Mr. Backe told us a homework which Show You Know in chapter 2.3.

Hello everyone.Today in class we talked about Jayden's number line post and we talked about Adding, Subtracting, Multiplying, and Dividing integers.We had to talk about Jayden's number line because the fractions were at the wrong place.


Here is an example of Jayden's picture:

Mr.B told us to talk to our tables and see what's wrong with it.I asked Renz P what's wrong with it and he said that -2/9 should be closer to zero and -4/7 should be after -2/9 i asked him why and he said becuase -2/9 is 0.2 and -4/7 is 0.5 so -2/9 should be closer to zero.

Here is an example that Mr.B gave us :


Here is the second one:


He told us to put each fractions in a different number line.

For the rest of the class Mr. B gave us Multiplying and Dividing Integers and told us to give 2 examples for each one.

Multiplying :

(+) x (+) =
(5) x (8) = 40
(7) x (5) = 35
(+) x (-) =
(8) x (-5) = -40
(9) x (-2) = -18
(-) x (+) =
(-6) x (7) = -42
(-4) x (7) = -28
(-) x (-) =
(-8) x (-5) = 40
(-2) x (-4) = 8

Dividing :

(+) ÷ (+) =
(3) ÷ ( 4) = 0.75
(4) ÷ (7) = 0.5
(+) ÷ (-) =
(4) ÷ (-9) = -0.4
(9) ÷ (-7) = -1.2
(-) ÷ (+) =
(-5) ÷ (4) = 1.25
(-9) ÷ (2) = -4.5
(-) ÷ (-) =
(-3) ÷ (-6) = 0.5
(-5) ÷ (-3) = 1.6

Homework for November 3,2009

Page 57,58 and 59 (syk)
and check your understanding (CYU). Then practice page 60 # 4 or 5, and each of # 8, 9, 10 and 11.

Well that's it for me,it took me 2 days to do this please tell me if there's any mistakes,errors or anything at all comment.Thats it for today and now i have to do math homework.BYE!
