Sum of  

5/13

and

7/13

in Simplest Form

Given:   +
Since the denominators are common (the same), we can add the numerators:
+ = =  is in Simplest Form since the Greatest Common Factor of 12 and 13 equals 1, GCF(12, 13) = 1
Therefore, the Sum of  

5/13

and

7/13

is equal to

12/13

in Simplest Form:  

5/13

+

7/13
