i think so, i get that you could also do something like this
[math]
\frac{a}{-1*b}
=
\frac{a*1}{-1*b}
=
\frac{a}{-1}
*
\frac{1}{b}
=
-a\frac{1}{b}
[/math]

the book is also did pic related, i'm aware that the 4 outside the parenthesis and the denominator inside are canceling out out, but why does it end up as a negative before even using the distributive property? chatgpt seems to be taking another route but it makes -3x/2 into a positive for some reason
