In skills we had to prove 2 different ways, if these two fractions 2/3 and 4/6 were greater, less than, or equal too each other. I did it in decimals and pictures. A key word we needed to think about was "precise".

DECIMAL: When you divide fractions you always divide the numerator by the denominator. 2/3 is 2 divided 3. Your answer will be 0.666 (repeating) Then you divide 4 by 6 and get 0.666 (repeating) Now you know that both of the fractions are the same or equivalent.

PICTURE:




2/3 and 4/6 are equal but not completely the same...
Even though they have the same amount of entirety that pieces they are cut into are different . They are also written differently .


The second question we
had to do was, 1/8 and 1/4. is 1/4 bigger - smaller - or equal to 1/8? To find the answer you need to do the same thing for this question like you did for the first. I'll show you in a decimal and a picture ...


DECIMAL: 1 divided by eight = 0.125
DECIMAL: 1 divided by four = 0.25


PICTURE


so you can see that 1/4 is bigger than 1/8
1/4 is cut into smaller pieces . would you rather have 1 out of four pieces or 1 out of eight pieces ?

skills homework (fractions)
Mr.Backe has been explaining to us for the last couple classes that even though fractions are equal in size they are not the same. Like my first example...
2/3 is greater, less then or equal to 4/6. Lets find out shall we :) Okay first we are going to find the decimals so we can compare them to see which is bigger.
DECIMALS

To find the decimal you have to divide the numerator by the denominator.

2 divided by 3 = 0.6(repeated)

4 divided by 6 =0.6(repeated)

so according to the decimals both fractions are equivalent, but we still aren't sure so lets try it with a picture.
PICTURE

Both the decimals and the pictures tell us that the fractions are equal, but they aren't the same. lets say we had a pizza and there was a chocolate and we cut it into 3 pieces and there was only two of us. All a sudden two more people come in and want some chocolate, so we cut each of the three piece in half. Now each of the four people get 1/6. Although the same amount was eaten, they got smaller pieces.

The next Example is 1/8 and 1/4, this one I will do the picture first.
PICTURE

Now according to the pictures 1/4 is bigger then 1/8, but just to b sure lets figure out the decimal.
DECIMAL

Once again to find the decimal you have to divide the numerator by the denominator.

1 divided by 4 = 0.25
1 divided by 8 = 0.125

Now that we also found the decimal we know that 1/4 is bigger hen 1/8 because if the whole is cut into 4 the pieces will be bigger then if you cut the whole into 8 pieces.

In skills class, Mr. Backe asked us two questions
they are:

Is 2/3 and 4/6 different or the same?how?
(Explain in two different ways)
Is 1/8 and 1/4 the same?
(Explain in two different ways)


1. Is 2/3 and 4/6 different or the same? how?

Both numbers are the same because if you convert them into a percentage they would be the same.
Like this:

2/3 = 66%



4/6= 66%

We could also convert them into decimal to prove that they are the same.

2/3= 0.66


4/6=0.66

By this it shows that they are the same.


2. Is 1/8 and 1/4 the same?

No, they're not.

1/8=0.125

1/4=0.25

By converting it by decimals it shows that it is not the same.

skills problem
















Two thirds and four sixths are the same because if you times the two and the the three from two thirds by two you get four sixths. In other words it's the same amount of a whole. Here is two different ways to explain it.











The next question was about one eighth and one fourth. Here is two different ways to proof that they are different.











These are precise ways of figuring out the bigger fraction.

For our skills home work we were assigned some fraction questions. We are expected to solve them and make a post about it.

To find the decimal you have to divide the numerator by the denominator.


2 divided by 3 = 0.6 (repeated)
4 divided by 6 = 0.6 (repeated)


This way the decimals should all be equivalent. Lets be sure by looking at this photo.











Picture taken by Rayna:P
This picture shows us that the decimals and the fractions are equivalent, but not the same.

Okay so .. our next question is 1/8 and 1/4. Here is the picture for that.










What the picture is showing us it that 1/4 is bigger than 1/8.
You always have to double check though, so to make sure lets figure out the decimal.

1 divided by 4 = 0.25
1 divided by 8 = 0.125


So we found the decimals and prouved that 1/4 is bigger than 1/8.
If the whole is cut into 4 the pieces will be bigger then if you cut the whole into 8 pieces.


JP's Skills Fraction Scribe

How is 2/3 and 4/6 the same or different? And is 1/8 and 1/4 the same?
(Explain in 2 different ways)

1. We can convert these fractions into Percents

2/3= 66%

4/6= 66%

2. We can convert them into decimals

2/3= 0.66

4/6= 0.66



1. Is 1/4 and 1/8 the same?

No they're not the same

We can convert them into another fractions using different numbers but still be the same amount.

1/4 = 75/100


1/8 = 2/16
