Let x--------> the unknown scale size we know that N 1---------> x N 2---------> 1 N 3---------> 0.937 N 4--------->0.878 scale factor=0.937/0.878------> 1.0672 to obtain the size N 3 ----> multiply the size N 4 by 1.0672 size N 3=1.0672*0.878-----> 0.937 so to obtain the size N 2 ----> multiply the size N 3 by 1.0672 size N 2=1.0672*0.937------> 1
to obtain the size N 1 ----> multiply the size N 2 by 1.0672 size N =1.0672*1------> 1.0672 hence x=1.0672-------> x=1.067
