Equivalent fractions represent the same value. Multiply (or divide) both numerator and denominator by the same number.<br><br>
&bull; \( \frac{3}{4} = \frac{3 \times 2}{4 \times 2} = \frac{6}{8} \)<br>
&bull; \( \frac{8}{12} = \frac{2}{3} \) &ne; \( \frac{3}{4} \)<br>
&bull; \( \frac{9}{16} \) &ne; \( \frac{3}{4} \)<br><br>
Final Answer: A: \( \frac{6}{8} \)
