- fractions, decimals, and percents can be used to represent numbers in various situations.
- percents can be written as fractions and as decimals.
- eg. 1/2% = 0.5%,
- 150% = 150/100

4.3: Percent of a Number

- you can use mental math strategies such as halving, doubling and dividing to find the percent of some questions.
- To calculate the percent of a number, write the percent as a decimal then multiply by that number.

- percents can be combined by adding to solve problems.
- eg. 5% + 7% = 12%
- To calculate the increase in a number, you can add the combined percent amount to the original number.
- eg. 12% of 100 = 0.12 x 100 = 12
- percents of percents can be used to determine amounts that result from consecutive percent increase or decreases.

Great post Kayla. Your post was very neat and organized. Also your video was great, but you should show the questions. In your post for 4.2, I think you should add more information.

ReplyDeleteHmm, a little late, but this post and video was really well done. You explained things really well, and you did this all within the time of 5 minutes too. You made a few mistakes, though. I suggest making a script or cue cards to look at while filming the video. Showing the questions would be very useful as well. Overall this was a pretty good post.

ReplyDeleteGreat post Kayla. Your written part was neat and organized. Your video was also well done but you should have showed us the question so we know what question you were talking about. Other than that, great job.
