Calculating percentages without a calculator can be quick and easy with these simple methods:
- Find 10%: Move the decimal point one space to the left. For example, 10% of 50 is 5.
- Find 1%: Move the decimal two spaces to the left. For instance, 1% of 200 is 2.
- Multiply for other percentages: To find 20%, double the value of 10%. For instance, 20% of 50 is 10.
- Add or subtract percentages: For 15%, add 10% and 5%. For example, 15% of 100 is 10 + 5 = 15.
