Compare dimensions

3 feet = 36 inches

4.5 feet = 54 inches

36 inches / 4 inches = 9

54 inches / 6 inches = 9

The scale factor is 9

I think that I too used to say " dilation `` but it should actually be `` dilatation ' ' ! !

k = 4•5 / 0•5 = 9

or

k = 3 / (1/3) = 9

My Oki (colour laser) and XEROX (B&W) printers do the calculations.

I just pick the size I want, and submit the image.

Then they print it out as required.

It’s 9x. 3 feet = 36 inches.

4 inch * x = 36x = 9

4.5 feet = 48 + 6 = 54 inches

6 * x = 54

x = 9

So the 4 x 6 picture needs to be increased by 9 fold.
