Percents are used everywhere. Percents are used to find discounts and sale prices. Stores are always having sales and items discounted. Percents can be converted to fractions and decimals. You can also find the percent of a number. If you own a business, you want to make a profit. Percents help you figure out how much you need to make to keep your business open and how much you need to pay your employees.

Parts Per 100

"Percent" means parts per 100. So, if I have 2 cents, then I have 2 cents out of 100 cents or 2 percent of a dollar. 2 percent is written as 2%. It is also written as 2/100 or .02 (said 2 one hundredths). It may seem like 2 percent (written as either: 2%, .02, 2/100) is not a big amount, and I surely would not run to the bank to cash a check for 2 pennies or $0.02! However, if someone offered me 2 percent of $500,000, I would put on my running shoes to cash that check.

Whether I am trying to figure out what percentage or fraction of someone's dollar belongs to me or how much is left over after I spend that money, I need to be able to understand the relationship between fractions, percents, and decimals.
