Robin's Final Percent Post

~ A percent means out of 100 and it's another name for hundreths which can be represented as a decimal or fraction
~Ex. 65% means 65 out of 100 or 65/100 or 0.65

4.1 Representing Percents

Key Ideas
To represent a percent you can use 100 grid charts. One shaded grid that has all the squares shaded in represents 100%. To show a percent that is larger than 100% you shade in more than one grid. To represent a percent between 0% and 1% you shade in a part of one square.

Fractional Percent - A percent that includes a portion of a percent.
Ex. 1/2%, 0.42%, 73/8%, 125 3/4%, 4.5%

4.2 Fractions, Decimals, & Percents

Key Ideas :
Fractions, decimals, and percents can be used to represent numbers in various situations.
Percents can be written as fraction as decimals.
Ex. 1/2%=0.5% 0.5%=0.5/100 =0.005
=1.5 or 11/2
423/4%=42.75% 42.75%=42.75/100 =0.4275

4.3 Percent of a Number

Key Ideas :
You can use mental math strageties such as halving, doubling, and dividing by ten to find the percents of some numbers.
To calculate the percent of a number, write the percent as a decimal and then multiply by the number.
Ex.121/2% of 50 = 0.125 x 50 = 6.25
121/2%=12.5 = 0.125

4.4 Combining Percents

Key Ideas :
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 number: 12% of 100 =0.12 x 100 = 12 100+12=120
~You can multiply the original number by a single percent greater than 100
Percents of percents can be used to determine amounts that result from consecutive percent increases or decreases.


  1. Good job, Robin! I like how you added lots of colour. Also, you included examples. Though, next time add in your video, link to your scribe and check for spelling because I found a few errors. Keep it up!

  2. GOOD JOB ROBIN! Your scribe is well organized and neat. I like the way you added colors but next time, try to only use it for important details, not for the whole section. Also, try to check over your spelling, add a video, link, or even some pictures. Keep it up!

  3. Good Job Robin! You indeed made your scribe very colorful, but as what Bennette had said, try using it for important words only. Next time,try adding in links, videos or picture, and remember to spell check your work. Keep it up!
