What is the method for converting a percentage to a decimal?

To convert a percentage to a decimal, you need to move the decimal point two places to the left. This process effectively changes the percentage (which is based on a part out of 100) into a decimal format. For example, if you have 75%, moving the decimal two places to the left gives you 0.75. This transformation is essential because it allows for easier calculations in mathematical operations, such as addition or multiplication, when working with percentages in decimal form.

The other methods outlined do not correctly achieve this conversion. Moving the decimal one place to the right would increase the value, while multiplying the percentage by 100 reverses the necessary conversion, turning a decimal back into a percentage. Adding a zero to the end of the percentage does not accurately reflect a conversion process and does not properly denote the proportional value out of one.
