Percentages express a proportionate part of a total. When a total is not given then it is assumed to be 100. E.g. 57% (read as 57 percent) can also be expressed as 57/100 or 57:100.Example: If 57% (57 percent) of your savings are invested in stocks, then 57 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 57*100 (i.e. $5700) are invested in stocks.

### Percentage sign (%)
