### Scribe Post -{November.16.2006}- [V 1.4]

So today we started off with a quiz. It was straightforward. It looked something like this....

We then had to finish the rest of the chart using what we have. Use this one for practice.

-------------------------------------------------------------------------------------------------------

After the quiz, we got to work on our new big sheet thingy for the "Equivalent" unit. We got started by brainstorming our defintions. We had to come up with some things that explain fractions, percents, decimals, and ratios.

Here's what i wrote down.....

FRACTIONS:

Fractions are a way of showing parts of a whole. Example, 3/4 shows that 3 parts out of 4 are shaded or different. There can be proper fractions, mixed fractions, or improper fractions. They are made up of a NUMERATOR ON TOP and DENOMINATOR ON BOTTOM. Numerator is the parts, and the denominator is how many parts you have in the whole. Proper fractions are like 4/5, mixed fractions are like 2 3/4, and improper fractions are like 10/3.

FRACTIONS-->DECIMALS
numerator {divide} denominator

FRACTIONS-->PERCENT
numerator {divide} denominator X 100

FRACTIONS-->RATIO
partI : partII
partI = numerator
partII = denominator - numerator

PRACTICE:
CONVERT ALL THESE FRACTIONS TO DECIMALS AND PERCENTS AND RATIO
1. 4/5
2. 7/13
3. 600/700

DECIMALS:

A decimal is a number that is not whole. Like 3.2 or 1.2. This means 3 wholes and 2 tenths of a whole, or 1 and 2 tenths of a whole. The parts of a decimal go from tenths, hundredths, thousandths, and so onth. Base 10 representative of values less than one.

FRACTIONS-->DECIMALS
numerator {divide} denominator

DECIMALS-->FRACTIONS
say it -->write it
0. 40 = 40 hundredths = 40/100 - 2/5

PRACTICE:
CONVERT ALL THESE FRACTIONS TO DECIMALS
1. 1/2
2. 6/13
3. 256/257

CONVERT ALL THESE DECMIALS TO FRACTIONS

1. 0.34
2. 0.56
3. 0.99

PERCENTS:

A percent is a part of 100. For example, 25% shows that 25 out of 100 is different. It consists of a number and a % sign. "Cent" means "100" in french.

FRACTIONS-->PERCENT:
numerator {divide} denominator

PERCENT-->DECIMAL:
percent / 100
46% = 0.46

PERCENT-->FRACTIONS:
% / 100
56% = 56/100

PERCENT-->RATIO:
% : 100 - %
partI = 100

partII = 100 - %
15% = 15 : 85

PRACTICE:
CONVERT ALL THESE FRACTIONS TO PERCENTS:
1. 3/4
2. 5/8
3. 678/1000

CONVERT ALL THESE PERCENTS TO DECIMALS AND FRACTIONS AND RATIO
1. 56%
2. 98%
3. 99%

RATIOS:

[EDIT://Nov. 17.06.]
I came up with some stuff for ratio. Kinda rough, and probably wrong. But here.

A ratio compares two quantities of something. It has 2 numbers and a colon in the middle. For instance, if you have 2 cokes, and 3 pepsis (or pepsus?) then the ratio of cokes to pepsis would be 2:3. You can include this in all your equvalent conversions by first converting to fractions:

RATIO-->FRACTION:

first number : second number.
first number + second number = DENOMINATOR.
first number = NUMERATOR.

FRACTION-->RATIO:
numerator = first number.
denonimator - numerator = second number.

PRACTICE:
CONVERT ALL THESE FRACTIONS INTO RATIOS
1. 4/5
2. 2/3
3. 7000/10000

CONVERT ALL THESE RATIOS INTO FRACTIONS
1. 5:3
2. 2:6
3. 1000:1

Another way of thinking of ratio is this:
Now you may have walked into a store and looked for a TV. You see 4:3 and 16:9 and all this crazy mumbo-jumbo. BUT. Wait. These are actually ratios. 4:3 means that the TV screen is 4/3 as wide as it is high.
(wikipedia)

Here's a website on ratios that i found while googling "sliced bread".

http://www.themathpage.com/ARITH/ratio-and-proportion_1-3.htm

There's a link to some problems at the bottom.

----------------------------------------------------------------------------------------------------------------

And Mr. Harbeck. Here's a comment i posted on that S3 Scribe Post Blog. And no, i didn't find it by searching "sliced bread" again. Instead it was "mini wheats" Ha. Just kidding.

So that's today's scribe post. Finish all those facts for tomorrow. Tomorrow's scribe will be......uh....MR. JUSTIN .

V 1.1. (some editing, fixed picture)
V 1.2. (updated defintions)
V 1.3 (added more conversions, fixed problems)

wow. haha thats such a good scribe =) haha i couldnt have done it better myself !!! what a nerd! haha anyways good job =)

Mr. H said...

Nice Scribe Mike. COuld you find a link to add to this scribe. Interactive games are always good to add as a link. Good use of colour and illustrations.

Mr. Harbeck

.:THE SOUP MAN:. said...

Wow...nicely done. That's gonna be tough to beat when I have to do mine lol

Anyway, liked the pictures and colours.

apuya_soldier_841 said...

k ill go to look for some game that works in to this i gues mr. h.

.:THE SOUP MAN:. said...

What on earth were you Googling sliced bread for? Anyway, nice editing.

Excellent post. I like the great detail and images

crippled =( said...

whoa unbeleivable!!!!!!your talented at that u should be the scribe everyday lol!!!

CONVERT ALL THESE FRACTIONS TO DECIMALS AND PERCENTS:
1. 4/5=.8=80%
2. 7/13.53=53%
3. 600/700=.85=85%

PRACTICE:
CONVERT ALL THESE FRACTIONS TO DECIMALS
1. 1/2=.5
2. 6/13=.46
3. 256/257=.99

PRACTICE:
CONVERT ALL THESE FRACTIONS TO PERCENTS:
1. 3/4=75%
2. 5/8=62.5%(63%)
3. 678/1000=67.8%(68%)

PRACTICE:
CONVERT ALL THESE FRACTIONS INTO RATIOS
1. 4/5
2. 2/3
3. 7000/10000

CONVERT ALL THESE RATIOS INTO FRACTIONS
1. 5:3=5/3
2. 2:6=2/6
3. 1000:1=1000/1

I never knew what to do...so i just did this...So yeah...

Hey good job Blueberry!!! LOL

Mr. Kuropatwa said...

This is a really great scribe post apuya_soldier_841!

Like Mr. Harbeck I thought the way you used colour to help explain things was really helpful. You spaced the information out really well so it was easy to read and follow what you were saying. I also liked the links that you included and that you looked some information up on wikipedia and didn't just copy and paste but included the source you got it from (not everybody trusts all the information on wikipedia -- do you know why that is?).

My favourite part came right at the end ... the list of version numbers and descriptions of the updates -- that was fantastic! What would advance this post to version 2.0? ;-)

Cheers!

apuya_soldier_841 said...

haha thanks for all the comments guys.

and Mr. Kuropatwa for all your questions, some people dont trust wikipedia cause anyone can change what it says, and maybe a version 2.0 would be a complete remake of this post.

and megs, most of it is right , but on..

CONVERT ALL THESE RATIOS INTO FRACTIONS
1. 5:3=5/3
2. 2:6=2/6
3. 1000:1=1000/1

its wrong.

ratios are not the same thing as fractions.

remember,
if partI : partII,
then partI = numerator
and part II = partI + partII.

why dont you try again.

Hey you made a very nice scribe Michael, I'll have to be in the "Scribe Hall of Fame" because you got in. >.< Anyways... I like your post. Great job !
