um i hope i am doing this right so umm how does this work..............OH I GOT IT
Mean, Median and Mode
The three ways of finding the average of a group of numbers.
MEAN- the average number
To find mean in a group of numbers you take the numbers and add them all together ex. 10 13 14 17.
STEP 1 STEP 2
10
13
14 10 divided by 4 = 13.5
+17=
54
You then take the Sum and divide it by the amount of numbers you used to get the sum. Ex 54 divided by 4 = 13.5
and that is your average 13.5
MEDIAN- the middle number when you allin sp.x a group of numbers.
Take several numbers ex. 2 4 1 3 6 and you arrange them from smallest to largest
STEP 1
1 2 3 4 6
and then find the middle number in the row and thats your median
EX 2 if you don't have a odd number of numbers ex 1 2 3 4 5 6 you allign them in order like before and take the 2 middle numbers and add them together and divide the sum by 2
1 2 3 4 5 6 in this case 3 and 4 = 7 divided by 2 = 3.5 and that is your median
MODE- the most amount of numbers
in a group of numbers you find the most common number
ex 2 4 5 4 3 1 so the mode in this would be 4 because there are 2 4s and that is how you find the mode
or
if there are two numbers that are more common like 22 33 4 5 the mode would be BOTH 2 and 3.
so ya this is my first blog and I hope you like it ps please comment on it yay

My Long Awaited Blog Post From Before Christmas
Interest
Today in class we learned about interest, to find the interest of any number you must multiply the principal by the rate.
Today in class we learned about interest, to find the interest of any number you must multiply the principal by the rate.
500 = Principal
.12 = Rate
1 = Time
500 x .12 = 60.00 x 1 = 60.00 = The interest is 60.00

Percent CHALLENGE!
Wednesday, December 13, 2006
More on Decimals, Percents, and Fractions
Today's class was about the title. Percent to Decimals, Decimals to Percent, and Percent to Fractions. The way you put a Percent into a decimal is divide the percentage into 100 and you will have your decimal form
.

.Here is an example of Percent to Decimals:--------------->
In the diagram you have to divide the percentage by 100 as you see in the diagram and once you finished then you will have the decimal form.
Here is an example of Deciamals to Percent:--------------->
In the diagram you have to move the decimal place to spots to the right so you have a whole number and then you have your number out of 100 your percent%.

Here is an example of Percent to Fractions:---------------->

Looking better!!
The comments to the Chicken Problem are awesome - it's great that some of you are beginning to post/comment. We still need to get our community built up. It would be great to see comments on other people's posts - remember to keep them positive and math-related. It's OK to offer more information/examples if you think that you have something the original poster might have left out. That's how we learn from each other. Come on.....let's get the comments going!

Percent,Fraction, and decimal
Today in class we learned percent, fraction, and decimal.
Now I am going to explain to you what we learnt.
First we learnt how to change percent to fraction,
18%= 18/100, because 18% is two digit number and percent is 100(whole) so,
it is 18/100 Fraction is 100(whole) is also so it changes to 18/100.
and the that number to decimal, First go back to 18% and just multiply by 100.

Understanding Percentages
Percent is a part of a whole, usually out of one hundred. Percent literally means “per hundred”. A percent is basically another form of writing a fraction and decimal. Fractions, decimals and percents are all one big happy family.
Percent is expressed in a percent sign like so: %
To get the most of a percent statement, think of it in this way:
A% x b = c
Percent of whole part
Percent can be used to see what percentage of Winnipeg people like to listen to Hot 103 to your percentage on a test.
Percentage is part of a whole like so:

What percentages of families have a ping pong table in their house?
Step 1: Get the fraction
Many families have ping pong tables (part):
how many families (whole):


Step 2: Reduce or multiply the fraction, so that the denominator is 100
In this case you would multiply both top and bottom numbers by 20 because 5 goes into 100 twenty time and whatever you do to one of the numbers you have to do it to the other number.

Step 3: Convert the fraction into a decimal

0.40
Step 4: Multiply the decimal by 100
0.40 x 100 = 40 40 % or families own a ping pong

Chicken Problem

OK, gang. I NEED YOU TO START POSTING, so here's a small challenge for you. In the diagram are 3 chickens, each with a different mass. Can you tell me how much each one weighs? Describe your process - how did you come up with the answer?
To post a comment, just click on the "comment" hyperlink at the bottom of the post. You will be required to put your user name and password in (the one you used to set your account up when we did it together.)

Scales
A scale model or diagram represents a specific object that is life-size. The scale model or diagram can be one half the size of the actual object or even one hundredth the size of the life-sized object. Scales are used when making a model of a building, a house, a playground and other objects. Scales are also used when someone wants to make a very small object bigger, just like a model or a diagram of a very small bug. Scales are usually expressed with two numbers with a colon between them or two numbers with the word “to” between them. For example, on a world globe there is a scale. The scale might say something like this: one centimetre is equal to 500 kilometres. This scale can be expressed like this: 1cm:500km or like this: 1cm to 500km.

Let’s say you found a doll that measures 12 centimetres tall and you want to find out how much one centimetre of that doll would stand up to yourself. (Let’s say you are 160 centimetres tall.) Take 12 cm and 160 cm and turn it into a fraction with 12 cm as the numerator and 160 cm as the denominator. And next to it, make another fraction with 1cm over x. Solve the proportion.

Ratios
Ratios are the relation between numbers, amounts, or degrees. Ratios compare two numbers. One could also use a ratio to compare one part to another part. Ratios can be seen by using fraction form, placing a colon between two numbers, placing the word “to” between two numbers, or by using a decimal.
Example: 3/2 = 3:2 = 3 to 2 = 1.5
To solve a ratio you need to find term 1 and term 2. The first number that comes in the sentence is term 1 and the second number is term 2.
Example: 3/2 = 3:2 = 3 to 2 = 1.5
To solve a ratio you need to find term 1 and term 2. The first number that comes in the sentence is term 1 and the second number is term 2.
