Ryans Final Percent Post

Percent
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.

  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.
