The length of the string that plays a D is found by setting up a proportion based on the given ratio 27:16. Since a 64 cm string plays a B, and B corresponds to the smaller number in the ratio (16), we can set up the proportion as 27/16 = x/64, where x is the length of the string that plays a D. Solving for x gives x = (27/16)*64 = 108 cm.
