Hi,         

Note:  It is necessary to find a common denominator to combine fractions.

As I understand the Question: the answer You refer to is incorrect.

 

   common denominator being 60

 3/20 = 9/60  and 1/12 = 5/60

  

    x = 4/60 = 1/15



CHECKING our Answer

1/15 + 1/12 = 4/60 + 5/60 = 9/60 = 3/20
