If the picture is k times the actual size, then that means that if something is of size 1 in the real world, then it is of size k on the picture. Thus, if something is of size 3cm on the picture, its actual size is 3/k cm. -Doctor Sebastien, The Math Forum Date: 4/8/96 at 8:34:35 From: Anonymous Subject: Re: ratio Dear Dr. Math, Thank you very much for the answer.
