Justin Gacilan's Final Percent Post

A percent means out of 100 it can be represented as a decimal or fraction.
example - 25% means 25 out of a 100 and , or 25/100 or 0.25

4.1 Representing Percents
To be able to represent a percent you need to use a grid chart out of 100, one shaded grid chart means that all the squares shaded in represents 100%. If you want to show a percent that is larger than 100% you need to shade in more then one grid chart. To represent a percent between 0% and 1% you would shade in one square.
Fractional Percent - A percent that includes a portion of a percent.
example - 1/2%, 0.42%, 73/8%, 3/4%, 4.5%

4.2 Fractions, Decimals, & Percents
Fractions, decimals, and percents can be used to represent numbers in many ways.
Percents can be written as fraction as decimals.
example - 1/2% = 0.5% 0.5% =
0.5/100 = 0.005
150%=
150/100
=1.5 or 11/2
423/4%=42.75% 42.75%=42.75/100 =0.4275


4.3 Percent of a Number
You can use strategies like doubling,halving, and dividing by ten to find the percent of the number.
To calculate the percent of a number, write the percent as a decimal and then multiply the number.

Justin Lorenzo's Final Percent Post

Percent means out of 100. It is also another name for hundredths and can also be expressed as fractions and or decimals.

4.1 Representing Percents Key Ideas : Shade squares on a grid of 100 squares called a hundred grid to represent a percent. A completely shaded grid represents 100%. If you shade more than one grid, that represents a percent greater than 100%. To represent a fractional percent between 0% and 1%, you have to shade part of one square. Also, to represent a fractional percent greater than 1% you have to shade squares from the hundred grid to show the whole number, then shade part of a square from the grid to show the fraction.

4.2 Fractions, Decimals and Percents Key Ideas : Percents can also be written as decimals or a fractions.

Ex. 1/2 = 0.50 = 50%

4.3 Percent of a Number Key Ideas : You can use mental math strategies such as doubling, halving, and dividing by 10 to find the percents of some numbers. Write the percent as a decimal and then multiply by the number to calculate the percent of a number.

eg. 12 ½ % of 50 = 0.125x50 = 6.25

4.4 Combining Percents Key Ideas : Adding percents can be used to solve problems.

Eg. Add combined percent with original number: 25% of 100 = 25. 25 + 100 = 125

Eg. Multiply the number by a single percent greater than 100: 125% of 100 1.25 x 100 = 125 Percents of percents can be used to determine amounts that result from consecutive percent increases or decreases.

~ 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

4.2 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
150%=150/100
=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.

The video is kinda blurry so you might not see it very well.
The ending got cut off due to my computer.


Here's a link to help you understand percents better!

The words might be oversized or undersized since it got lagged and became like that. If not ignore this.

A percent means out of 100, also another name for hundredths and can be expressed as decimals or fractions.

Representing percents

Shade squares on a grid of 100 squares called a hundred grid to represent a percent. A completely shaded grid represents 100%. If you shade more than one grid, that represents a percent greater than 100%. To represent a fractional percent between 0% and 1%, you have to shade part of one square. Also, to represent a fractional percent greater than 1% you have to shade squares from the hundred grid to show the whole number, then shade part of a square from the grid to show the fraction.











Fractions, Decimals, Percents

Percents can also be represented as a decimal or a fraction.
Eg. 80% = 0.8 = 4/5


Percent of a Number

You can use mental math strategies such as doubling, halving, and dividing by 10 to find the percents of some numbers. Write the percent as a decimal and then multiply by the number to calculate the percent of a number.
Eg. 14 1/2% of 60 = 0.145x60 = 8.7


Combining Percents

Adding percents can solve problems, for example; 5% + 6% = 11%.

To calculate the increase in a number, add the combined percents to the original number.
Eg. 15% of 100 = 0.15x100=15, 100+15=115
Or multiply the original number by a single percent greater than 100.
Eg. 115% of 100 = 1.15x100 = 115

Percents of percents can be used to determine amounts that result from
consecutive percent increases or decreases.

Percent - means out of 100. Example 50/100

4.1 Key Ideas: To represent a percent you can use 100 grids. 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 on grid. To represent a percent between 0% and 1% you shade in a part of one square

4.2 Key Ideas: Fractions, decimals, and percents can be used yo represent numbers is various situations. Percents can be written as fractions and decimals.

4.3 Key Ideas: You can use some mental math strategies such as doubling, halving, or dividing by 10 to find percents of some numbers.

4.4 Key Ideas: Percents can be combined by adding to solve problems. You can ass the combined percent ammount to the original number. Percents can be used to determine ammounts that result from consecutive percent increases or decreases. You can multiply the original number by a single percent freater than 100.
