Final Percent Post

Definition of percent:
any number out of 100,that can be represented as a fraction and a decimal.

Key Points of Chapter 4


When showing a percent greater than 100%, use more than 1 grid.
When showing a percent less than 1%, but more than 0%, use only one grid.


Percents can be shown as a decimal and fraction.
50% = 1/2 and 0.5

To calculate a percent of a number,write it as a decimal and multiply it.
15 1/2% of 50= 0.125x50
= 6.25

To combine a percent, put them,or add them together.
ex.1% + 2% = 3%
To found out the increase in a number, add the combined percent to the original number.
5% + 7% = 12%

  1. Roemer, great post. Your post was very easy to read, but you shouldn't make it rainbow because people can have dufficulty reading it. You used colour so it didn't bore me while I was reading it, you should add some colour to the '4.4' and things so it would be easier to identify. Other than that, great job!
