This is super simple I guess but my mind has gone blank.
I have these dimensions below, and I am trying to scale this rectangle to 610 wide
Width 560 Height 315
From these figures, how do I work out the percentage to scale the height so the rectangle is still at the same aspect ratio?
Think I got it...
560 / 100 = 5.6
610 / 5.6 = 108.92
