Ryans Final Percent Post

Means out of 100
Another name for hundredths
65 % means 65 65 out of hundred or 65/100

Chapter 4.1 Representing Percents
You can represent a percent by using grids.
ex. If you have a 155% and you need to present it using grids, you have to have 2 100 grids to show it. One grid has 100 boxes which means a 100%, so you have to shade 1 whole grid and in the second grid, shade 55 boxes.

Chapter 4.2 Fractions, Decimals, and Percents
You can convert or represent decimal, fraction and percent.
ex. 36% = 0.36 = 36/100 or 4/25

Chapter 4.3 Percent of a Number
You can find the percent of a number by writing the percent to decimal then multiply it to the number.
ex. 160% of $53.27 = 1.60 x 53.27 = $ 85.23

Chapter 4.4 Combining Percents
You can combine percent to another percent to solve problems. (5% + 7% = 12%)
ex. A girl bought a shoes that costs $150. Adding to this cost are the P.S.T. which is 7% and G.S.T. 5%. You may add the P.S.T and the G.S.T which is 12 % and the whole cost is 112%. Divide the 112% to hundred, 1.12, then multiply it to the cost of the shoe, $150 x 1.12 is equal to $168. This is the amount that you need to pay.

My percent video


  1. Great job Ryan. It's great you have the summary key ideas of the chapter and also your video. Your post was very organized but, you should add some color to some important words.

  2. Good job, Ryan. It would have been nice if you explained your thinking for the video, though. Your post listed all the key points in each chapter, but I think color would have been nice to add as well.

  3. Great job Ryan. Your post was very neat and your your video was also good. Next time add some colors to how the key points in the summary. Other than that, great job.
