Marilen's Final Percent Post

Percent means out of 100. Also, it is another name for hundredths. You can represent percents by using decimals and fractions as well.
eg. 100%, 1, 100/100 or 1/1 .

4.1 Representing Percents
- You can shade squares on a hundred grid, and a fully shaded grid represents 100%.
- Shade more than 100%, b
y using more than one hundred grid.
- Fraction percents can be shaded in by shading in less than 1 square.
- Shade squares to represent the whole number and shade part of one square to represent the fraction.

4.2 Fractions, Decimals, Percents
- Percents can be written as decimals and fractions
eg. 50%= 0.5= ½

4.3 Percent of a Number
- Halving, doubling, and dividing by ten are methods to find percents of some numbers.
- You can find the percent of a number by converting to a decimal, then multiplying by the number.
eg. 12 ½ % of 50 = 0.125x50 = 6.25

4.4 Combining Percents
- Adding percents can solve problems.
- To find the increase of a number.
• Add the combined percent to the original number.
eg. 12% of 100 = 0.12 x 100 = 12 + 100 =112
• Multiply the original number by a single percent greater than 100.
eg. 112% of 100 = 1.12x100 = 112
- Percents of Percents can be used to determine amounts that result from consecutive percent increase or decrease.
