How do you express a decimal as a percent?

To express a decimal as a percent, you move the decimal point two places to the right and then add the percent sign. This method is based on the fact that "percent" means "per hundred." Thus, multiplying a decimal by 100 is equivalent to moving the decimal two places to the right. For example, if you have the decimal 0.75, moving the decimal two places to the right turns it into 75, and then adding the percent sign results in 75%.

This approach effectively converts the decimal into a format that expresses the value out of 100, which is the standard for percentage calculations. Knowing this conversion method is essential in various applications, whether in calculations related to grades, financial transactions, or statistical data.
