Sum of  

-4/13

and

10/13

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 6 and 13 equals 1, GCF(6, 13) = 1
Therefore, the Sum of  

-4/13

and

10/13

is equal to

6/13

in Simplest Form:  

-4/13

+

10/13
