It depends upon where you put the parentheses in the question.

there is no parentheses in the math problem

But when you type out the expression on a single line, you need paretheses to define the order of operation.

There are many ways a person could interpret what you have typed, and all give different answers.

Two possibilites would be
3x - (27/25) /[(x-9)/15x]
and
[(3x-27)/55] / [x-(9/15x)]
