Evaluate

Question

\[\dfrac j4\] when
\[j=12\].

Answer 1

To evaluate \(\dfrac{j}{4}\) when \(j = 12\), we substitute \(j\) with 12:

\[ \dfrac{j}{4} = \dfrac{12}{4} \]

Next, we perform the division:

\[ \dfrac{12}{4} = 3 \]

Thus, the value of \(\dfrac{j}{4}\) when \(j = 12\) is

\[ \boxed{3} \]
