To find the product of \( \frac{1}{4} \cdot 10.2568 \), we can analyze the nature of the numbers involved:
- \( \frac{1}{4} \) is a rational number.
- \( 10.2568 \) is also a rational number (it can be expressed as \( \frac{102568}{10000} \)).
The product of two rational numbers is always rational. Therefore:
- The correct response is: Rational, because both numbers are rational.
