This chapter is about percents, fractions, and decimals.

Percent means: out of 100. Another name for percent is hundredths.

Representing Percents:

You can represent a percent using a hundred grid.

One fully colored grid shows 100%

For example is 20 squares are colored it represents 20%

Fractions, Decimals, and Percents:

Percents can be represented as a fraction or a decimal.

For example:

Percent of a number:

You can use mental math strategies like halving, doubling, and dividing by 10.

For example: 50% of 200 is 100.

Combining Percents:

You can combine percents by adding them together to solve a problem.

For example: The cost of a shirt is 7.99. What is the total cost of the shirt including 5% GST and 7% PST.

5%+7%=12%

100%(the cost of the shirt) +12%= 112%

112% as a decimal is 1.12

7.99 x 1.12 = 8.9488

= $8.95.
