There are two possible solutions: 18/26 = 27/39 18/26 = 9/13 - Divide both terms by 2. 27/39 = 9/13 - Divide both terms by 3 18/27 = 26/39 18/27 = 2/3 - Divide both terms by 9. 26/39 = 2/3 - Divide both terms by 13. I still do not know how to find either solution in a logical mathematical manner. Last edited: Feb 11, 2012
