The re-posting of the Problem that Noody Can Solve

There are three boys each have 10 cents each. They want to buy a soda which costs 25 cents. So they give their money to another boy and ask him to buy the soda for them. Ps: they ask for the change back! So the boy goes gets their soda and gives them the change back. There is 5 cents change. So the three boys divide it amongst them selfs. There is one cent left over so one of the boys keeps it forhimself. Which means they actually only spent 9 cents each. 9x3=27 And the boy who took 2 cents equals 29. Where is the last penny? So if you know the answer leave a comment behind. It took me 5 minutes. See if it takes you this long!

Mixed Fractions

By: Marygrace Dela Cruz

Definition of a mixed fraction:
- mixed fractions are a combination of a whole number and a fraction.
- it can be converted into an improper fraction.

Example:

Lowest Common Denominator

IM SO SORRY THIS IS LATE :'(

okay today we did this in class .. so it would be easier for me =P .. i'll put EXACTLY what mr.hanley put
LCD: is the lowest common factor between two or more denominators
WHY(do we use LCD's)?
- it makes fraction operation easier
- makes less mistakes

{EXAMPLES}
this is a test question. Its from the test that we did last week. It showed what people did CORRECTLY but not the easy way .. i guess the teachers are trying to make math a little easier ? hmm .. i'll keep thinking that way =P

this is a picture of one of the other examples we did .

sorry this is so messy [8] stay up tonight

Kim's Scribe Post

Hello, I have volunteered or have been assigned to do a scribe post on Adding Fractions.
But I would like to explain what fractions are (even though I wasn't assigned to do so). Do you know what fractions are? Well, there is 4 well known kinds of fractions, a proper fraction, improper fraction, mixed fraction and equivalent fractions. Fractions that represents a part (numerator) over a whole (denominator) , that would be called a proper fraction. When a fraction is representing something with a numerator that is larger than the denominator, that would be called an improper fraction. A mixed fraction is when you have a whole number and a proper fraction. Last but not least, an equivalent fraction is when two (or more) fractions equal the same. Below is an bubble share presentation that would help you understand more about fractions.

Now onto adding fractions. First, I'm going to start off with:

Below is a bubble share presentation that would lead you through and show you how to add fractions with the same denominators.

Now, I am going to show you how to add fractions with different denominators below:

If there is anything that I have done wrong, please feel free to comment and tell me =)

...

*Equivalent Fractions!!!

WHAT are they ?

ONE HALF and TWO QUARTERS equal the same thing because HALF OF FOUR equals TWO. Half of a half is one quarter, so two quarters equal a half. As I have just proved here, equivalent fractions are two or more fractions with the same value. They are the same besides the fact that the sizes/pieces are smaller. Think of it as a cake. The more people you have to share with, the smaller the pieces get.

The best way to find equivalent fractions is to reduce the two or more fractions into their smallest value. I showed this in my bubbleshare using pictures =) Okay, so this post is finally done =)

Subtracting Fractions With Like Denominators

Fractions:
Fractions are parts of a whole that has a numerator (the part) and a denominator (the whole; can't be a zero).There are three types. Which are proper( 3/5), improper(5/2) and mixed(1 1/2) fractions which can be simplified and can't have decimals.

Can you subtract? If yes, then you can subtract fractions with like denominators.

Here's my illustration: The steps are mentioned!

Subtracting Fractions With Unlike Denominators

Subtracting fractions with unlike denominators is not harder it just takes a little longer. You have to find the CD (Common Denominator)

Common Denominator:
Common Denominator is when you have fractions with the same denominator.

Here is my illustration about common denominators:

If I made any mistakes kindly tell me pls.

mixed fraction to improper Scribe

Definition for improper
• nominators is bigger then the denominator

• there is no decimals

• the numerator is the part and denominator is the whole

Example

To find mixed number to improper fraction

example 4 5/7

1. first you want to x 7 x 5 = 35
2. then you want to add 35 + 4 = 39

To find improper fraction to a mixed number

example 8/28

1. first you have to find how many times 8 goes into 28 = 3 = 3 x 8= 24
2. now you have to subtract 28 from 24 and you will get 4
3. now you leave 8 as the denominator then you will have 3 24/4

If i was not suppose to do mixed fraction then tell me and i will take it out

A Problem that Nobody Can Solve!

Okay here i go...

9x3=27 And the boy who took 2 cents equals 29. Where is the last penny? So if you know the answer leave a comment behind. It took me 5 minutes. See if it takes you this long!

Common Denominators

Well in my bubbleshare i will be explaining how to find the common denominator. I hope its enough effort cuz it took me a long time to make it.

Proper Fractions

A proper fraction is when the numerator is less than the denominator. Remember the numerator is the part and the denominator is the whole. If the numerator is bigger then its an improper fraction. Here's an example of a proper fraction:

3/10

3 is the part (numertaor)

10 is the whole (denominator)

Scribe 03/05/07

SUPRIISE its mee =) .. we did a test today .. it was about fractions and we got the whole class to do it .. homework is DO THE BIG PAPER .. its DUE ON TUES. MARCH 6 / 07 .. ALSO .. its MONIQUES birthday tomorrow .. so HAPPY BIRTHDAY =) .. okay thats all =)
