The solution follows the methodology demonstrated in Example 1 of the provided context. First, the inequality is simplified by dividing by the positive coefficient 24, which maintains the inequality sign. The resulting boundary is $x < 25/6$ (approx 4.16). For part (i), natural numbers are positive integers starting from 1, so we list values less than 4.16. For part (ii), integers include negative numbers and zero, so the solution set extends infinitely in the negative direction.
