Final Percent Post

1. Percent - means out of 100 and it can be shown as decimals and fractions.
For example 80% can be 0.8 and 8/10.
Representing Percents;
You can represent a percent by using a grid.
For example 20% can be shown like this.
Percents can also be shown as decimals and percents. For example 50% can be 0.5 or 1/2.

Percent of a Number
You can use mental math strategies like halving, doubling, and dividing by 10 to find a percent of a number. You can also write the percent as a decimal then multiply it by the number.
For example,
12 1/2 % of 50 = 0.125 x 50 12 1/2% = 12.5%
= 6.25 = 0.125

Combining Percent
You can combine Percents to solve a problem.
For example if your buying a bike for $100 and the tax is 5% PST and 7% GST = 12%.
You can find the answer buy finding 1% of $100 then multiply by 12 to find how much the tax would be with the original price. So 100 divided by 100 = 1 then multiply by 12 and you will find the tax which is $12. All together you are paying $112 for the bike.
