Write the fraction as a percent. \( \frac{9}{20} \) \( \frac{9}{20}=\square \% / \) (Simplify your answer.)

To convert the fraction \( \frac{9}{20} \) into a percent, you can multiply it by 100. So, \( \frac{9}{20} \times 100 = 45\). Therefore, \( \frac{9}{20} = 45\% \). You can also think of the conversion process as moving the decimal: \( \frac{9}{20} = 0.45\), and when you multiply by 100, you just shift the decimal point two places to the right to find 45. This simple trick can make percentage calculations a breeze!
