Answer 2

Answer:

Step-by-step explanation:

TO VERIFY, 9/11+2/13=2/13+9/11

LHS= 9/11+2/13      [LCM OF 11 AND 13=143]

       =[9*13]+[2*11]/143

      =117+22/143

      =239/143

      =     96

         1 ---------

             143

RHS = 2/13+9/11

       =22+117/143

      =239/143

=            96

         1 ---------

             143

:.LHS=RHS
