Ok, i sort of get it but i don’t. 1:1 is square 16:9 means it’s 1.77 x’s wider than it is tall. But what the hell does 9 actually represent considering it comes in many sizes from small to large yet same ratio, so what makes one side 9 or what ever? For instance why not just say 1.77:1?

Nine units of measure in the Y direction. It doesn’t have any intrinsic units, it’s only meaningful in relation to the other part of the ratio.
In the specific case of image aspect ratios, it’s a unit of length–any unit of length. For every 16 of those units in the X direction you’ll have 9 of the same unit in the Y direction. The unit can be pixels, points, inches, furlongs; doesn’t matter. All the ratio cares about is how many of them there are in relation to each other.
