### John's Final Percent Post

Chapter 4 Understanding Percent

4.1 Representing Percent
-Percent means out of 100
-Another name for hundred
Ex. 65 means out of 100 or 65/100 or 0.65

4.2 Fraction, Decimal, Percents
-Fraction, decimals, and percents can be used to represent numbers in various situations
-Percents can be written as fractions and as decimals
Ex. 1/2 = 50% or 0.50

4.3 Percent of a Number
-You can use mental math strategies such as halving, doubling, and dividing by ten to find the percents of some numbers
-To calculate the percents of a number, write the percents as a decimal then multiply by the number
Ex. 12 1/2 of 50 = o.125 x 50 = 6.25%

4.4 Combining Percents
-Percents can be combined by adding to solve problems. 5% + 7% = 12%
-To calculate the increase in a number
-You can add the combined percent amount to the original numbers
Ex. 12% of 100 = 0.12 x 100 = 12

My Percent Video:

1. Great post John, Your post was well organized and your video was explained good.Nex time you should add some bold or color to your writting.

2. I agree with Paul, colour would make important words stand out much more, and make your post appear less plain. Also, aren't the final percent post and the percent video two different posts?

3. Great job John. Your post is really organized and neat. Next time add some colors and also bold some key words to make it stand out like what the others said. Other than that, great job.

4. Great post. Your definitions were bery clear and well organized. Your video was well done as well!
