Trying to find the scale for a 77 centimeter by 53 centimeter painting to fit on a 8.5 by 11 inch paper. Please show me how-

11/8.5 = 1.294

77/53 = 1.452

So, the 8.5x11 paper is closer to square than the 53x77 paper

The scale will have to be such that the height of 77cm will fit in 11in

That is 11in:77cm or 1in:7cm = 2.54:7 = 1:2.75
