To solve the inequality \(-12m < -24\), we proceed as follows:
- Divide both sides by -12. Remember that when you divide or multiply both sides of an inequality by a negative number, you must flip the inequality sign.
\[ \frac{-12m}{-12} > \frac{-24}{-12} \]
This simplifies to:
\[ m > 2 \]
Thus, the solution to the inequality is:
m > 2.
