Diorella's Final Percent Post

*A percent means out of 100. It's 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 represented as a decimal or a fraction.
Ex. 3/4 = 0.75 = 75%

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.
Ex. 20 1/2 % of 40 = 0.250 x 40 =10

4.4 Combining Percents Key Ideas :
Adding percents can be used to solve problems.
Ex. Add combined percent with original number:
25% of 100 = 25. 25 + 100 = 125
Ex. 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.
