Finding Percentages by Using Decimal Method - Knowing how to find percentages from different format is a valuable skill and is beneficial when doing your finances. Whether you are mentally estimating your expenses, modeling your loan on a spreadsheet, or using a calculator, you need to understand how decimals and percentages are related. If you have an idea of how interest rates, then you might have noticed that most interest rates are written in decimal form. The decimal form of these interest rates signifies the percentage. The decimal form helps do calculations. There are several ways of achieving the decimal form: - The simplest one is dividing by 100. For example, converting 85 percent into decimal form. We will divide 85 by 100 to get 0.85 as a result, which is the same as 85% in decimal form. - Another way to achieve this is by moving the decimal places. For example, 85 is the same as 85.00. For converting it to the decimal form, we will move the decimal places to two places to the left. The result we will get is 0.85. The method works even on the complex numbers. Here are some examples; 100 percent becomes 1 or 1.00 : 77.343 percent becomes 0.77343 : 0.6 percent becomes 0.006. These worksheets and lessons focus on the use of decimals to find the value of percentages.
