How can you convert a percent back into a fraction or decimal?

To convert a percentage back into a fraction or decimal, one divides the percentage by 100. This process is based on the definition of a percent, which literally means "per hundred." When you take a percentage, such as 75%, it can be expressed as 75 out of 100, or 75/100. To convert it into a decimal, you simply perform the division: 75 divided by 100 equals 0.75.

This method highlights the relationship between percentages and their fractional and decimal equivalents, making it a straightforward approach for conversions. Understanding this is essential for tasks involving percentages in various fields, including nursing, where calculations related to medication dosages often require comprehension of percentages in different formats.
