A number k is greater than 3. Which of the following is true about 승 ? 1 It is between 3 3 It is equal to 1 It is greater than 1

Alekssandra [29.7K]

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.
