If the number k is greater than 3, we have the following inequality:

$k>3$

In order to evaluate k/3, let's divide the inequality by 3:

$\begin{gathered} k>3 \\ \frac{k}{3}>\frac{3}{3} \\ \frac{k}{3}>1 \end{gathered}$

So the expression k/3 is greater than 1, therefore the correct option is D.

in order to get the percentage you would just need to divide 6,840 by 38,000 (6840/38000 = .18)

this gives you .18

.18 is equivalent to 18%
