To find a fraction equivalent to \( \frac{5}{20} \), you can simplify it by dividing both the numerator and the denominator by their greatest common divisor, which is 5 in this case.
\[ \frac{5 \div 5}{20 \div 5} = \frac{1}{4} \]
So, \( \frac{1}{4} \) is an equivalent fraction to \( \frac{5}{20} \). Other equivalent fractions can also be generated by multiplying both the numerator and denominator of \( \frac{1}{4} \) by the same number (e.g., \( \frac{2}{8} \), \( \frac{3}{12} \), etc.).
