3) What should be added to 11/6 to get 12?​

Answer 1

Unknown number be x  

11/6 + x = 12  

L.C.M. of 1,6 is 6  

11 + 6x/6 = 12  

11 + 6x = 12 x 6  

11 + 6x = 72  

6x = 72 - 11  

x = 72 - 11/6  

x = 61/6  

verification  

11/6 + x = 12  

11/6 + 61/6 = 12  

11 + 61/6 = 12  

72/6 = 12

12 = 12
