### Carlor's Scribe post: Textbook pages 142-143

4.)

- For this questions it says that use your mental math to solve them so please try to trust your brain first rather than your finger.

- You can do solve these questions the fast way but for now let's do the slower way so that it is more understandable.

A.)

-For this question it's asking for the 20% of 60, so first we need to find 10 %.

- Now we know that 6 is 10% of 60 but what we're looking for is 20% so we need to multiply by 2 or you can also add by 6.

- So there it is we found 20% of 60 which is 12.

B.)

- For this question they are asking for 250% of 400 but, we know 400 is equal to 100% so we only need to double that to get 200% which would be 800. So, now the problem is 50%.

And all we have to do is divide it by 2.

- Now we know all the parts of our percent, we only need to add all them up.

800+200= 1,000 so, there it is 250% of 400 is 1,000!

C.)

- For this question it's asking us for 10.5% of 100. We know that 10% of 100 is 10 so we only have to find 0.50% of 100. In order to find it we have to find 1% in which we would divide by 2 to get 0.5%

- Hey, it's 1! so we divide it by 2 to get 0.5% which would be 0.5. And all we have to do is add up- 10+0.50= 10.5. There it is 10.5% of 100 is 10.5 they're the same!

7.)

A.)

- This question is asking what are the chances of winning with one ticket and expressing them in percents.So, we need to use this formula to get the percent or chance = (amount divided by total)x100= percentage

Because we are finding the chances of one ticket we need to set that (1 ticket as the amount and divide it by 200 as the total tickets sold) and multiply it by 100= percentage or the chances.

1st-

2nd-

- Woah! There it is the chance of winning with one ticket is only 0.5%.

B.)

- For this question we need to find how many tickets we have to buy to get 2.5% of winning.

- But, we already know that 1 ticket have a 0.5% chance winning.

- So we only need to find what 2.5% percent would equal to.

Answer- It's 5!

11.)

- For this question they are looking for 6.5% of 9 984 670 square kilometre.

- So we need to find 1% and add it to get 6% next, we need to find 0.5% and add it all up.

- Now we know that 1% is 99846.7, we need to multiply that to get 6% which would be 599,080.2.

- Our problem now is 0.5 so we will find it.

- It's 49937.35! So we add it all up 599,080.2 + 49937.35= 649017.55!

- That's it! 649017.55 squared kilometre is the area of Manitoba compared to the area of Canada.

Here is a video which demonstrates more about how to get percent of a number. Enjoy!

That's the end of my post and Thanks for viewing!

I'm sorry I posted it up really late! I'm really sorry guys :/

### Kassey's We Day

**MY WE DAY EXPERIENCE**

There were so many people that inspired me like " Hannah Taylor, Spencer West, Mia Farrow, Rick Hansen, Craig Kielburger, Marc Kielburger, and so many more. I couldn't believe that me just that one person could do something about changing the world but with the help of them all saying " What we've got to do is put the power and responsibility in the hands of the communities" or "If enough of us choose to change even one small thing, together we have the power to change anything" and one I mostly remember is "you are never to young to change the world".

Together WE can make a difference just like all of those inspiring people.

IT STARTS WITH ....

**ME**

**AND ENDS IN ....**

**WE**

Also during the We Day celebration Craig and Marc always made us say WE ARE by saying the we committing to changing the world. Also they talked about the vow of silence. That is for children who have no right to speak out and they have to work and be in child labor. On November 30,2011 I will the participating in the vow of silence and i hope YOU WILL TOO.

Join making a difference and being a part of we day! Let those people inspire you to make a difference in the world and trust me after hearing the speeches I want to go to Kenya or build a anything to put a smile on someones face.

### raeesa's we day experience!!

**millions**of young people are denied their right to an education,health care,security,and their inherent right to life. which I think is really wrong.

**Spencer West**, he inspired me the most because at a young age he found out from the doctors that he might never be able to walk again. Spencer heard that but new that just because he would never be able to walk again doesn't mean he should give up in life. So he kept going in life just like you and me, he tried to make his story about his legs funny so people would understand it doesn't matter what you look like or your story we are all the same,and we should all be treated equally.

**me to we concert**!!!

10. When water frezzes, it's volume increases by 10%.

a) By how much does the volume of 750 mL of water increase when it frezzes?

750 / 100 = 75%

b) 750 + 75= 825

14. 4% of 100 is the same as 8% of what number? Explain how you arrived at your answer.

4% of 100 4 x 2 = 8 100 x 2 = 200 So, 8% of 200

1% = 1 2% = 1

1% = 1 2% = 1

1% = 1 2% = 1

__1% = 1__

__2% = 1__

4% = 4 8% = 4
