Given the expression:
[tex]\frac{3}{4d}[/tex]To evaluate this expression when d=6, implies that we substitute this value into the expression.
Thus, we have:
[tex]\begin{gathered} \frac{3}{4(6)} \\ \end{gathered}[/tex][tex]\begin{gathered} \Rightarrow\frac{3}{24} \\ \Rightarrow\frac{1}{8} \end{gathered}[/tex]
