Patrick's percent post

Welcome to my percent post!

Part 1.
Describe how you would find 50%
We divide the number by 2

Describe how you would find 10%
We divide the number by 10

Describe how you find 1%
We divide the number by 100

Describe how you would find 25%
We divide the number by 4

Percent: It is a number that is out of 100

Part 2.


This is how you represent 180%












This is how you represent 12 3/4%

This is how you represent 0.7%

Part 3. 

1) 26%- Percents to Decimal:

Divide the percent by 100 to get the decimal

26%÷100= 0.26

Decimal to fraction:

Find out the place value of the last digit behind the decimal to find the denominator. Once it`s found you take away the decimal to find the numerator.

26/100

2) 7/10- Fraction to Decimal:

Divide the numerator by the denominator to get the decimal

0.7

Decimal to Percent:

To get the percent from the decimal we multiply the number by 100 because a percent is out of 100

3) 0.024- Decimal to Percent:

Multiply the decimal by 100 to get the percent

0.024÷100= 2.4%

Percent to Fraction:

To find the numerator we take out the decimal and that becomes our numerator. To find the denominator we find the place value of the last digit behind the decimal to get the denominator.

24/10

Part 4.

1) 20% of 60

10%-0.6 

10%-0.6

0.6+0.6=1.2

20% of 60= 1.2

2) 0.1% of 40

1%- 0.4

0.5%- 0.2

2.5%- 0.1

1.25%- 0.05

0.6%- 0.025

0.3%- 0.0125

0.1%- 0.00625

0.1% of 40= 0.00625

3) 250% of 400

100%- 400

100%- 400

50%- 200

250% of 400=1000

Part 5.
 

Show you know page 148: What is the final sale price at each store? Which is a better buy? Explain you thinking.
Store A: 50% off one day only
Store B: 25% off one day followed by 25% off the reduced price the second day

For example the price is $360.00

Store A: 50% of $360.00
Divide the price by 2 because it explains 50%
$360.00÷2= $180.00
The final price for store A is $180.00

Store B: 25% off original price
Divide the price by 4 because it explains 25%
$360.00÷4= $90.00= discounted price
Divide the discounted price by 4 to reduce it the second day
$90.00÷4= $22.50
The final price for store B is $22.50

Store B is a better buy because we save more money when we buy the item.

The better deal is when you take 25% off the original price and then taking another 25% off the discounted price because instead of taking 50% off the original price you take 25% off the discounted price.

Making a Bar Graph

Hi guys, here is a cute video about making a bar graph.  Can you do it better than them?

Introducing Blogging

A Colleague of mine Mr. Kuropatwa created this post for his students. Since it is Internet Safety Week please pay attention to the videos below.

Blogging is a very public activity. Anything that gets posted on the internet stays there. Forever. Deleting a post simply removes it from the blog it was posted to. Copies of the post may exist scattered all over the internet. I have come across posts from my students on blogs as far away as Sweden! That is why we are being so careful to respect your privacy and using first names only. We do not use pictures of ourselves. If you really want a graphic image associated with your posting use an avatar -- a picture of something that represents you but IS NOT of you.

Here are a few videos that illustrate some of what I want you to think about:

Two teachers in the U.S.A. worked with their classes to come up with a list of guidelines for student bloggers.

One of them, Bud Hunt, has these suggestions, among others:

1. Students using blogs are expected to treat blogspaces as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. While we encourage you to engage in debate and conversation with other bloggers, we also expect that you will conduct yourself in a manner reflective of a representative of this school.
2. Never EVER EVER give out or record personal information on our blog. Our blog exists as a public space on the Internet. Don’t share anything that you don’t want the world to know. For your safety, be careful what you say, too. Don’t give out your phone number or home address. This is particularly important to remember if you have a personal online journal or blog elsewhere.
3. Again, your blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover some really hateful and immature things you said when you were younger and more prone to foolish things. Be sure that anything you write you are proud of. It can come back to haunt you if you don’t.
4. Never link to something you haven’t read. While it isn’t your job to police the Internet, when you link to something, you should make sure it is something that you really want to be associated with. If a link contains material that might be creepy or make some people uncomfortable, you should probably try a different source.

Another teacher, Steve Lazar, developed a set of guidelines in consultation with his students. You can read them here.

Look over the guidelines and add the ones you like in the comments section below this post; either from one of Steve's students or one of your own. I think Bud's suggestions are excellent. We'll be using the one's I highlighted above as a basis for how we will use our blog.

Cheers,
Mr. K.

I could not have written it any better. Enjoy blogging and use your head. Thanks
