That is not quite correct, although it is becoming more and more popular in textbooks.  Personally, I continue to object to it.

The Order of Operations wants us to do things of the same preference in left-to-right order.  If we do this strictly, you have just written h = (V/l)*w and this is not what you intend.  If we forget about that rule and just do what we want, hoping people will understand, then you have written h = V/(lw), which is exactly and unambiguously correct.

In my personal opinion, it is incorrect without the parentheses.  Not everyone agrees with this assessment.

Like I said, it is becoming more popular.  I am currently reading a text book on statistics - point estimation.  The author liberally uses the notation without the parentheses.  I find it annoying.
