Answer
$\le$
Work Step by Step
The Multiplication Property of Inequality states that if a positive number $c$ is multiplied to each side of $a \le b$, then $ac \le bc$.
Thus, if $3x \le 12$, then, multiplying $\frac{1}{3}$ to each side of the inequality gives:
$3x(\frac{1}{3}) \le 12(\frac{1}{3})
\\x \le 4$
Thus, the missing inequality symbol in the given statement is $\le$.
