No, there isnt a box that you can enter percentages, but thats not essential.
Doubling the pixel width in the size box is the same as 200%, whats wrong with doing this if acuracy is needed?
You can drag the image handles to resize and reposition the image.
This 500 x 500 pixel image shows the ruler measure the cursor measure and size box in the inspector which can be used to resize an image.

I know that I can double the pixel width or drag a corner. With that said, what if I want to scale an image by 350% or 325% and original is 371 px wide? Now I need a calculator every single time I scale an image. I am creating a series of 30 Keynote presentations and each will have dozens of images. This is going to get really old, really fast.
In summary ... it's not "essential," but it would be terribly useful.

I would be very interested what your requirements are that you need to use percentages.
I dont know anyone that uses pecentages in digital imaging these days. In the days of making photo compositions for printing plates is was the only way to do it.
For screen based presentations and page layout, percentages are irrelevant. Tables, graphs, shapes, stills or video, are sized to fit a space or a presized image holder. They are all simply placed and sized by dragging handles to the required size. It couldnt be quicker and easier.

I have written two engineering textbooks, each of which have thousands of figures. Each figure is saved in PDF and EPS format. I am using Keynote to create lectures based on these books. Looking at the following screen shot:
you see what the PDF file looks like when it is first inserted and the scaled size I wish it to have. It turns out that scaled size is a little more than 300%. Since I want all the figures in the lectures to have the same scale, I have to do this hundreds of times. I don't see how dragging handles will achieve this and I certainly don't want presized image holders.
So yes, it could be much easier.

From what you say there is no specific reason to work with percentages in Keynote as you are scaling images to a convenient size, not a specific enlargement factor.
I don't see how dragging handles will achieve this and I certainly don't want presized image holders.
Its very easy to learn how to resize images, select the image then click on one of the handles until is resizes to what you want. This is the main tool to position and size in Keynote and most other Mac applications.
Use the ruler to mark out guides to the position and pixel size you want, duplicate the slide as many times as you need to have guides in each slide. Drag in the images onto each slide and scale using the image handles. They will snap to the guides to help placement.
Draw a rectangle shape and position and size it, then lock it to the slide (command L)
Drag in the images onto each slide and scale using the image handles, they will snap to two of the sides to help placement.
It took me just over two minutes to accurately place and resize 10 images of completely different pixel sizes, so this method is very fast and very precise. I hope to reassure you this method is used by the print, broadcast TV and graphics industry and I am sure will help you accomplish your end product.

Your solutions do not achieve this.
My suggestion exactly achieves what you say you want to do.
Create a guide set or a positioning frame to the pixel size you need, then position all your images against them and they will be sized correctly.

That would make all the images the same size in pixels. That would mean that all images, no matter what the original size, would be the same width or height as every other image. That is not what I want. I want a 100 px wide image to be 320 px wide and a 250 px wide image to be 800 px wide (with the vertical dimensions scaled proportionally). Get it?

As I have established, that there is no input for percentage resizing within Keynote. You can produce any pixel size image you want, 10 different sizes in a single slide or 100 slides with 100 different image dimensions, what ever your final image requirements are can be accomplished in Keynote.
I indeed GET IT here, but you need to GET IT that you can only use the tools that are available within Keynote, there are no other tools available.
I have outlined a number of options that Keynote has but if these tools are not to your liking look for another application.

Your first reply made it clear that a percentage adjustment did not exist.The problem is that you just kept giving me solution after solution that were not applicable to my problem. I am not upset that the solution I want doesn't exist, I am amazed that you kept giving me erroneous solutions. I am also surprised about your attitude that made it look like I was being an idiot when it was you who was giving me inapplicable solutions.
Have a good night.

when it was you who was giving me inapplicable solutions.
I have only suggested achievable ways to resize images with the tools Keynote has because they actually work.
The thing that intrigues me is that I don't know why you want to calculate changing image size using a percentage, I am not saying its wrong, I am saying its a very unusual way to work and I am genuinely interested in what your trying to do.
You haven't said why you need to do it this way, can you please explain?
