To determine if the fractions \( \frac{5}{20} \) and \( \frac{1}{4} \) are equivalent, we can use cross-multiplication.

1. Cross multiply the fractions:
   - Multiply the numerator of the first fraction by the denominator of the second: \( 5 \times 4 = 20 \)
   - Multiply the denominator of the first fraction by the numerator of the second: \( 20 \times 1 = 20 \)

2. Since both products are equal (20 = 20), the two fractions are **equivalent**.
