Answer

Two rational numbers greater than \( \frac{1}{4} \) are \( \frac{1}{3} \) and \( \frac{1}{3} \). Their product is \( \frac{1}{9} \), which is less than \( \frac{1}{4} \).

Solution

We want two rational numbers, say x and y, such that both x and y are greater than 1/4, yet their product is less than 1/4. A simple example is to take   x = 1/3 and y = 1/3. Let's check: 1. Both numbers are greater than 1/4 since 1/3 (approximately 0.333) is larger than 0.25. 2. Their product is (1/3) · (1/3) = 1/9, which is approximately 0.111. Clearly, 1/9 is less than 1/4 (which is 0.25). Thus, the rational numbers 1/3 and 1/3 are examples that meet the requirements:   x = 1/3 > 1/4, y = 1/3 > 1/4, and x · y = 1/9 < 1/4.

One example of two rational numbers that are greater than \( \frac{1}{4} \) but whose product is less than \( \frac{1}{4} \) is \( \frac{1}{2} \) and \( \frac{1}{3} \). Both \( \frac{1}{2} \) and \( \frac{1}{3} \) are greater than \( \frac{1}{4} \) since \( \frac{1}{2} = 0.5 \) and \( \frac{1}{3} \approx 0.33 \). When we multiply them together, \( \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} \). The value \( \frac{1}{6} \) is approximately \( 0.1666 \), which is indeed less than \( \frac{1}{4} = 0.25 \). Another pair can be \( \frac{5}{16} \) and \( \frac{3}{8} \). Here, \( \frac{5}{16} \) (which is around \( 0.3125 \)) and \( \frac{3}{8} \) (approx. \( 0.375 \)) are both greater than \( \frac{1}{4} \). Their product is \( \frac{5}{16} \times \frac{3}{8} = \frac{15}{128} \), and since \( \frac{15}{128} \approx 0.1171875 \), it's also less than \( \frac{1}{4} \). These pairs showcase how you can find rational numbers fitting the parameters you requested!
