Chapter 4 is based on Percents, Represent Percents, Fractions Decimals and Percents, Percent of a number and Combining Percents.

4.1 : Representing Percents

- Percents are always out of 100.

- Percents are often shown using hundred grids.

- Another name for percents is hundredths.

For Example:

65% is 65 out of 100.

4.2 : Fractions, Decimals, and Percents

- Fractions, decimals, and percents can be used to represent numbers in a various situations.

- Percents can be written as decimals and as fractions. (They are reversible)

For Example:

50% = 0.50 = 1/2 or percent = decimal = fraction (order doesn't matter)

4.3 : Percent of a Number

- To calculate the percent of a number, turn the percent into a decimal by dividing by 100, then multiply the decimal by the number.

For Example :

12½% of 50 = 12½ ÷ 100 = 0.125

0.125 x 50 = 6.25

4.4 : Combining Percents

- Percents can be combined by adding to solve problems.

- Percent is used in stores for discounts and taxes.

For Example :

5% GST + 7% PST = 12% Taxes

$100 shoes + 12% taxes = $112

$100 ÷ 100 = $1 x 12 = $12.00

$100 + $12 = $112.00

What is a Percent?

A percent is a fraction always represented out of 100.

Good job, Kevin! I liked your selection of color, but next time stick to only one or two main color.
