How to detect exact location of mouse click on sprite in scratch

I would like to detect the exact location of the mouse click within the 3x3 grid displayed on the screen. How can this be done in MIT scratch? Any suggestions?

This is pretty simple if you want to involve 2 variables in this: All you really need to do is to set the mousex position to a variable and the mousey position to a variable after the sprite detects a click on it. Here is an example:https://i.sstatic.net/9LAvM.png

There are two ways to do this.
You could create 9 sprites, hide, and use the When this sprite clicked event... ...but it would be a whole lot of unnecessary sprites.
Or you can do the following:
As @PullJosh said, you can use the mouse x and y blocks. Just do some math:
You know that the stage goes from X: -240 to 240, Y: -180 to 180.
Just put that into some code to detect ranges, below is a link to a project that is an example of this:

(Note: This assumes the grid boxes are the same size.)
