To effectively convert decimals to percents, it's crucial to understand what each term represents. Decimals are numbers expressed using a decimal point to separate the whole number part from the fractional part. For instance, 1.35 is a decimal where 1 is the whole number, and 35 is the fractional part. Percents, on the other hand, represent a part out of 100. The term 'percent' literally means 'per hundred.' Therefore, when you are converting a decimal to a percent, you are essentially determining how much of 100 the number represents. This relationship is key to understanding why the conversion process involves multiplication by 100. Once you grasp this concept, the steps involved will make more sense and seem more logical.

Multiplying a decimal by 100 is the main operation required to convert it to a percent. This step is straightforward but fundamental. Let's illustrate using the given example of 1.35: To convert 1.35 to a percent, you multiply it by 100. This is based on the idea that percent means 'out of 100.' To multiply by 100, you can simply move the decimal point two places to the right. So for 1.35, moving the decimal two places to the right gives us: 1.35 × 100 = 135 This multiplication transforms our decimal into a whole number (or a new decimal if the original one was smaller), giving us the numerical part of our percent value. It's helpful to remember that every time we multiply by 100, we're making the number 100 times larger, effectively scaling it to fit into the 'per hundred' definition of percent.

After multiplying the decimal by 100, the final step is to add the percent sign to the resulting value. Adding the percent sign (%) is a way to denote that the number represents a part out of 100. In our example with 1.35, after performing the multiplication 1.35 × 100 = 135, we simply append the percent sign to give us 135%. This sign addition is crucial because it indicates that the figure is now understood as a percentage, rather than just a regular number. Therefore, the result of converting 1.35 from a decimal to a percent is expressed as 135%. This final step ensures clarity and communicates the value in percent terms, making the conversion complete and officially recognized.
