1. Let's clarify the problem statement first: it appears you are asking why the value of \( d \) is \( \frac{3}{4} \).\n\n2. Typically, \( d = \frac{3}{4} \) arises from solving an equation or evaluating a ratio where the numerator is 3 and the denominator is 4.\n\n3. Without more context, a common example is solving for \( d \) where \( d = \frac{3}{4} \) means that the quantity \( d \) represents three parts out of four equal parts, or \( 0.75 \) in decimal form.\n\n4. If this value came from a proportion or algebraic equation, consider an equation like \( 4d = 3 \), solving for \( d \) by dividing both sides by 4, yielding \( d = \frac{3}{4} \).\n\n5. Please provide the original equation or context if you want a detailed step-by-step explanation.
