InDesign - Scale Selected Graphic to a Specific Percentage

Hello all,
Using InDesign CS 2017
This seems to be more difficult than it should be? I am looking for a way to scale a selected “graphic” within a frame by a specific percentage, i.e., 75%

I am hoping somebody can help me out here?

tell application id "com.adobe.InDesign"
	activate
	tell document 1
		if class of item 1 of selection is in {rectangle, oval, polygon} then
			try
				set ImagType to image type name of graphic 1 of item 1 of selection
				set theImage to graphic 1 of item 1 of selection
				set theImage to item 1 of selection
				select graphic 1 of item 1 of selection
			end try
		else if class of item 1 of selection is in {image, PDF, EPS} then
			set imageType to image type name of item 1 of selection
			try
				set theImage to item 1 of selection
			end try
		end if
		
		-- Here is where I would like to scale selected image by 75 perecent
		
	end tell
end tell

Thanks,
-Jeff

My apologies but I no longer need this answer, but I have not deleted the post in case somebody in the future is looking for the same thing?

All I needed was as follows:

set horizontal scale of item 1 of selection to 75
set vertical scale of item 1 of selection to 75

Thanks,
-Jeff
