### 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. 5% (read as 5 percent) can also be expressed as 5/100 or 5:100.Example: If 5% (5 percent) of your savings are invested in stocks, then 5 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 5*100 (i.e. $500) are invested in stocks.

- To find 15%, find 10%, then add 5%
- To find 20%, find 10% and double it
- To find 25%, find 50% and then halve it
- To find 26%, find 25% as above, then find 1%, and then add these two values
- To find 60%, find 50% and add 10%
- To find 75%, find 50% and add 25%
