Jamodin's Post - Fractions, Decimals and Percents

What we did in class today is learn how to change from fraction to decimal to percent but you can do it any which way.

The first thing we did was change a fraction into a decimal.
To do that, we just have to divide the numerator with the denominator.
Ex.









The second thing we did is change the decimal to a percent.
To do that, we have to multiply the decimal by 100 because percent is out of 100.
Ex.









That is the way you can do it but don't have to do it that way because there are other ways you can do it too.

You can change from decimal to fraction to percent and percent to fraction to decimal

Decimal to fraction to percent
Decimal to fraction. First, whatever number that is after the decimal is 1 in the denominator. Second, you count how many numbers are before the decimal. If the number is 2, then there will be 2 zeros and you put the zeros before the 1 in the denominator.
Ex.









Fraction to percent is you just have to make the denominator 100 and what you do to the denominator you do to the numerator.
Ex.








Percent to fraction to decimal
Percent to fraction is if the number is not a decimal. First, you just have to take the percent number and put it as the numerator and make the denominator 100.
Ex.










But if the percent is a decimal, you just count how many numbers are there before the decimal, you add a 0 at the bottom as a denominator to how many there are. Whatever the number is after the decimal, you put a 1. Then you put the percent number the numerator and make the denominator the number that you made by how many numbers before the decmial plus the 1 that is after the decimal.
Ex.









Fraction to decimal. It already says it at the top.

Here is a video that might help you if you still need help.

Jamodin's Pay It Forward

Part 1
Pay it Forward starts with one person that made a random act of kindness without any benefits. Then when they helped three people, those three people helped three other people each and those three people help another three people each and well you get the picture. It is just like a chain reaction or like a good disease that spreads helping other people by doing a random act of kindness without any benefits. If it doesn't work because some people forget to pay it forward,


Part 2
My Pay it Forward was cleaning up peoples yards. I chose this activity because I wanted to make a difference in someones life. I helped 3 people. I cleaned up peoples yards. I did my act of kindness on Nov. 12,2011.



Part 3
Our act of kindness went well. We helped out people by cleaning there yards. I felt good that I was helping people. They were surprised and then happy that we could help out. We did ask the people to pay it forward. They were willing to help out others too.

Part 4
The idea of Pay it Forward is important because the world isn't good but one person can make a difference and change peoples lives. I think my act of kindness made a difference because the people we helped out were happy and we know that they will make other people happy too.

Jamodin's Graphing Post

1. There are 5 different types of graphs. They are:

Bar Graph
Advantages - Comparing a set of data across categories.

Disadvantages - Can't compare two or more different sets of data

Double Bar Graph
Advantages - Comparing two sets of data across categories.

Disadvantages - You can only compare two sets of data.

Line Graph
Advantages - Showing changes in data over time.

Disadvantages - You can only use continuous data.

Circle Graph
Advantages - Comparing categories to the whole in percent.

Disadvantages - It is hard to compare categories.

Pictographs
Advantages - Comparing data that can easily be counted and represented using symbols.

Disadvantages - If the icon or symbol is cut , it is hard to tell if it is cut in half or in a quarter etc.

2. 3 ways graphs can be misleading is:

Distorting the scale

Distorting the visuals

Distorting the size of bars

2. a) A line graph and a bar graph

b) Yes i would continue selling Pizza Subs. The graph explains my answer because it is showing that in each week, the items that are sold are getting higher.

4. If I was trying to convince Mrs. Mota to continue selling healthy choices in the canteen, I would choose the line graph.

4. a)

Jamodins Proportion Post

Ratio - A comparison of quantities that have the same units.
Ex.







Rate - A comparison of two quantities measured in different units.
Ex.








Proportion - States that two ratios are equal.
Ex.







1. 5 hours to travel 360 miles is about _____mph.








2. As a playgroup worker , if I increase the amount of apple juice I am serving at the playgroup from 25ml to 100 ml, how much should I increase the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 to start with.








Three ways of proving if equivalent ratios are true is:





























Answer: 3/4 = 12/16 is true
4/9 = 16/72 is false












1. No it does not seem fair.

2. No its not fair because the man stole $100 and he surrendered it and he go 15 years in jail while the Ex-mortgage stole $3 billion and he got 3 years in jail.

3.I would send the Ex-mortgage CEO 30 years in jail and the man 1 year in jail.
