Nicole's fraction thingy

1)Use a picture and text to show that you understand what expressing fractions in lowest terms means.



2)how are improper fractions and mixed numbers are the same.

3)Find a web site or blog that explains how to create equivalent fractions in lowest terms. Create a link to it and a breif description of what this site has to offer.
http://www.webmath.com/index.html
ok this site has many different things that you can do but to get to the thing you want -click on the down arrow next to Quick jump to math help:-click on Fractions, reducing then it will bring you to a place where you enter a fration and it will calculate the answer and tell you how it got that answer.

4)Write a word problem that involves adding these two fractions with denominators of forths and thirds and your answer should be an improper fraction.
B) Write a word probem that involves subtracting two mixed numbers.

Kassie had 2/3 of a pie and 3/4 of a cheesecake in one night. How much dessert did she eat in one night.
B) that same night Kassie's brother Jordan had 9/10 of the money he was saving and spent 2/5 of it at the store how much does he have left?

5)Go to three peoples growing posts and answer their problems by leaving a comment. One of them has to be from from someone not in your home room.
Ok.





A)
[your answer should be 17/12]

B)
[your answer should be 1/2 OR 5/10]

Ashley's Fraction Growing post


Part 1

Question 1.


Question 2

Question 3
Website
This website has a good explanation on how to simplify and reduce fractions. Along with pictoral examples. It also has print out games and worksheets to do.

Question 4

a) Earl had 3/4 of a chocolate cake and 5/3 of a blueberry cheesecake. How much cake did he have altogether?

b) Horris had 3 3/5 chocolate bars. Later he gave 2 1/3to his bestfriend Horhay. How many chocolate bars did Horris have left?

Question 5

I answered Katho's , Rebecca's , and Aldrin's questions.

Question 6
Website
This website contains colourful pictoral examples and good explanations that are easy to understand.

Part 2

Question 1

Question 2



Question 3

Multiplying website
This website has a good explanation on how to multiply fractions and whole numbers and colourful examples. It even has a game to help you practice.

Question 4


Question 5

Dividing website
This website explains how to divide fractions by fractions, and when you click next lesson, it shows how to divide fractions by whole numbers. At the bottom of the page are timed games to test your brain with dividing fractions.

Question 6
I think the four people who should be in the "Growing Post Hall of Fame" are Rebecca, Yvanne, Ingrid, and I didn't chose anyone from 41 yet because there isn't much to chose from. I chose these people because they all had good explanations and they all included numerical and pictoral examples.

Question 7

If I had 35 cupcakes and I had to spilt it between 7 people, how many cupcakes would each person receive?

I answered Rebecca's word problem.

Becky's scribe
sorry it's late!

There are two parts to a fracton, there is the denominator and a numerator.

The denominator is the bottom part of a fraction It tells you how big or small the parts are

The numerator is the top part of a fraction. It says how many parts of the whole

If the numerator and the denominator are the same then you have 1 whole.
If the numerator is larger than the denominator than it is an improper fraction, or you have more than 1 whole.

(The first one is halfs the seccond is thirds, and the third is eighths)

As the denominator gets bigger the the equal parts get smaller

Kay uhhhh in class we learned about Equivalent Fractions.

To make an equivalent fraction you have to break the denomenator into smaller piececs. 1/2 = 3/6. You have the same amount but different sizes.




















To make an equivalent fraction you need to change the numerator and denomenator equally. Like so...

Improper Fractions


Today, we talked about improper fractions and mixed fractions... they were quite easy and not that hard to understand... we had a homework sheet which i finished before the class ended... and yea i think thats it... by the way we also finished the big paper =P

Some extra marks -kathleenf.

1.
volume = Length x Width x Height = 1120 x .5 = 560 x 4 = 2240 m³

3.
5 x 5 = 25
25 x 5 = 125
25 x 5 = 125

then you multiply each by 2 because there are six sides.
25(2) = 50cm²
125(2) = 250cm²
125(2) = +250 cm²
-------------

550cm²

Some extra marks for the test


3. If you have five 5 cm by 5 cm x 5 cm aluminum cubes and superglue them together in a row, what is the surface area of the resulting shape made by the five cubes?

One cube is 150 cm so for 5 cubes it will be 750 cm... How? because 150x5=750 cm

Note:
Sorry thats the only one i can answer. the other ones are confusing and my brain is hurting...Harbeck! i dont know im my answer is right... just tell me 2moroe if its right or wrong ok? bye

bonus question thingy

1) 1120 x 4 x .5 = 2240 m 3

2) 3.14(.3)(.3)
=3.14(.09)
=0.2826 x 3 = 0.8478 cm 3

i think it will only take about 1 second because if you estimate the voloume of the cylinder is .08 m3

3)
2x25x4 = 200
5 x 5 x 2 = 50

200+50=250cm2

mr. harbeck i cant post pics it wont work...nd i dont noe if dis is corect cuz the way you change the cm into m is confusing me

triangular prisim


To find the volume of a triangular prisim you multiply the base times the height times the length then divide by 2. To find the total surface area of a triangular prisim youfind the area of the base, sides and triangles then add theses together.

VOLUME OF A CYLINDER

The total surface area is made up of a circular top and bottom, which are each the same size, and the side surface, which is actually a rectangle.We must find the area of the top, which is the area of a circle with a radius of r. (Did you get it???..)

We did this today...LoOk!!! :Phaha..

Today in math we made a hamburger/hotdog paper and named it Volume.
(from the notes)
1.) triangular Prisms


2.) Area of the base triangle times the height will be the volume.
3.)

The Rockers Scribe (:

This is my second scribe (: coz i rock?! im right!

Well today, harbeck gave some test to calculate the cylinder, then jump to the next lesson: finding the volume of rectangular prism and triangular prism. down there shows what we did today:




well i work hard for that! just do the scribe for harbeck or for math. anyone there will do the scribe? then you ROCK . haha ;)

Norielle UR Scribe!!

First of all no one did the scribe today so i decided to do it myself... And i also did it because i understand the lesson today so..yeah...
1. today, harbeck showed us how to calcute the total suface area of a cylinder...he gave us steps on how to get the Total Surface area..SEE IMAGE:










Then he gave us some works to do...
he showed us more examples so that we could understand it more.
i guess i covered all the things we did today in class...
Next SCRIBE NICOLE
