Beyond the Answer
To convert \( 28\% \) to a decimal, you simply divide by 100, which gives you \( 0.28 \). To express it as a fraction, you start with \( \frac{28}{100} \) and simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 4. This results in \( \frac{7}{25} \). For a fun context, did you know that percentages date back to ancient Rome? They used a similar concept for tax collection. Today, understanding percentages can empower you to make informed decisions about things like budgeting or shopping sales, so getting them down to a science helps in everyday life!
