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%, by 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.
