2/7 + 1/14  

 

We need to determine a common denominator for each term       2/7 + 1/14

In this usage, the word "common" means they're the same 

By observation we see that one common denominator is 14 

So multiply 2/7 by 2/2 to obtain 4/14                                             4/14 + 1/14 

 

Now the addition is simple                                                             4/14 + 1/14  =  5/14
