set up the proportion 10/16 = x/28 28 x 10 / 16

It means the photograph is 10 inches wide by 12.5 inches long.

Ratio of new length to old length = 12/8 = 3/2 So ratio of new width to old width must be 3/2 New width/Old width = 3/2 so New width = Old Width * 3/2 = 6 inches*3/2 = 9 inches

The scale factor is 3:1

Not necessarily. The conversion factor from feet to inches is 12.

If the photograph is 4" wide and the mural is 80" wide then the scale is 4:80 which simplifies to 1:20. That is, 1" on the photograph is represented by 20" on the mural. If the photograph is 5" long, then the equivalent length of the mural is 5 x 20 =100"
