\( 20\% \) of \( 45 \) is **9**.

Solución

To calculate \( 20\% \) of \( 45 \), you can use the following method: 1. **Convert the percentage to a decimal:** \[ 20\% = \frac{20}{100} = 0.20 \] 2. **Multiply the decimal by the number:** \[ 0.20 \times 45 = 9 \] So, \( 20\% \) of \( 45 \) is **9**.

To find \( 20\% \) of \( 45 \), you can convert the percentage into a fraction or a decimal. \( 20\% \) as a decimal is \( 0.2 \). So, you can calculate \( 0.2 \times 45 \), which equals \( 9 \). Therefore, \( 20\% \) of \( 45 \) is \( 9 \). To make it even handier, remember the formula for percentage: \( \text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}} \right) \times 100 \). If you needed to find out what percentage \( 9 \) is of \( 45 \), you could rearrange the formula! Just another cool math trick to keep in your back pocket!
