I would start off by simplifying the fraction below.

$= (-9/3)$ = 3

And then divide -54 by -3 which will give you a positive answer of 18.

Did you manage to obtain 18?

$18$

Given,

$-54/(-9/3)$

Rewrite the expression as

$=-54*-3/9$

... since dividing by a fraction is the same as multiplying by its reciprocal.

As $54$ and $9$ can be divided by a common factor of $color(red)9$ , their values are reduced.

$=-54color(red)(-:9)*-3/(9color(red)(-:9)$

Simplify.

$=-6*-3/1$

$=color(green)(|bar(ul(color(white)(a/a)color(black)(18)color(white)(a/a)|)))$
