Here is your answer.
Let the number is x

ATQ
$x \times ( - 18) {}^{2} = ( - 3) {}^{ - 1} \\ \\ x \times 324 = - \frac{1}{3} \\ \\ x = - \frac{1}{3 \times 324} \\ \\ x = - \frac{1}{972}$
Therefore the number is - 1/ 972



$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope\:it\:helps\: you}}}}}}}}}}}}}}}$

$\huge\boxed{\texttt{\fcolorbox{Red}{yellow}{Be brainly!!!}}}$

Answer 2

Here is your answer

$x \times 18 {}^{2} = - 3 {}^{ - 1} \\ x = \frac{1}{3 \times 324} \\ x = \frac{ - 1}{972}$

So Number multiply by -1/972 to get -1/3
