### Percentage examples

Percentages express a proportionate part of a total. When a total is not given then it is assumed to be 100. E.g. 30% (read as 30 percent) can also be expressed as 30/100 or 30:100.Example: If 30% (30 percent) of your savings are invested in stocks, then 30 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 30*100 (i.e. $3000) are invested in stocks.

### History of Percentage

Before the Europeans learned about the decimal system, ancient Romans used fractions in the multiples of 1/100. An example was when Augustus levied a tax of 1/100 called centesima rerum venalium on goods sold at auctions. Computation with these fractions was similar to percentages.In the Middle Ages, denominator of 100 became more common. By the 16th century, as decimal system became more common, use of percentage became a standard. It was used to compute profit and loss, interest rates etc.
