Trying to use a single variable instead of two

Unity Engine
1

Is there any way I could write the code below in just one variable and have the same result in Debug.Log

var selectorX:int = (Input.mousePosition.x/Screen.width) * 5 + 1;
var selectorXScaled = selectorX * 100;
Debug.Log(selectorXScaled);

What the code basicly does is that it gives me a number 1>5 depending on where on the screen u clicked horizontaly.

var selectorXScaled = ((Input.mousePosition.x/Screen.width) * 5 + 1)* 100;
Debug.Log(selectorXScaled);

Thanks but that gives results like 123, 245, 455 and so on…I want results like: 100, 200, 500

var selectorXScaled = Mathf.Floor(((Input.mousePosition.x/Screen.width) * 5 + 1))* 100;
Debug.Log(selectorXScaled);

Thanks!
