Checking size images in Publisher in percent

[Illustrator Pascal]

Hello,
If I want to change the size of an image, I can do this by selecting the image and enter a value in the transform panel for W and H.
But what can I do when the proportions arent right anymore and I want to fix that?
Or what if I want to set the width at 100 % and height at 60 % of the original size ?
The transform panel don't shows percentages.

use math, enter the following after whatever is in the height field. * 0.6 or you could replace whatever is in the field with 60%

Thanks. I didn't knew the field was also a little calculator   Good to know.
And how can I reset the proportions when these aren't correct anymore?

If you are talking about a Placed image in a Publisher document, then select it with the Move Tool, and you'll see a field like this in the Context Toolbar:

If you click on the pulldown, you can adjust the image scale, including returning it to its original size/scale.

I found it. Thank you.
Problem solved.
