To get the ratio and the percentage between two dimensions. The first one is the the width and the second argument is the height.
$ propor 1600 900

To get the opposite dimension of a ratio use the following method. When you want to get a height, send the value after the flag --width and then the width and height. To achieve the opposite, send the height value after the --height flag.
$ propor 1600 900 w 16
The result for this will be something like this:
The proportional height is: 9
$ propor 1600 900 h 9
The result for this will be something like this:
The proportional width is: 16
