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.
