Let's calculate this step-by-step:
- First, divide 19 by 20: [ \frac{19}{20} = 0.95 ]

-
Result: Therefore, 19 out of 20 equals 95%! 🎉
Quick Reference Table
Here’s a quick reference table showing how different fractions compare to percentages:
<table> <tr> <th>Fraction</th> <th>Decimal</th> <th>Percentage</th> </tr> <tr> <td>1/2</td> <td>0.5</td> <td>50%</td> </tr> <tr> <td>3/4</td> <td>0.75</td> <td>75%</td> </tr> <tr> <td>19/20</td> <td>0.95</td> <td>95%</td> </tr> <tr> <td>1/10</td> <td>0.1</td> <td>10%</td> </tr> <tr> <td>9/10</td> <td>0.9</td> <td>90%</td> </tr> </table>
Common Mistakes to Avoid
