Sum of  
-5/6
and
1/6
in Simplest Form

Given:  
-5/6
+
1/6

Since the denominators are common (the same), we can add the numerators:
-5/6
+
1/6
=
-5 + 1/6
=
-4/6
However,  
-4/6
 is NOT in Simplest Form since the Greatest Common Factor of 4 and 6 does not equal 1, GCF(4, 6) ≠ 1
Upon inspection, the GCF(4, 6) = 2
In Simplest Form,  
-4/6
=
-4 ÷ 2/6 ÷ 2
=
-2/3
 (1 is the only factor common to 2 and 3)
Therefore, the Sum of  
-5/6
and
1/6
is equal to
-2/3
in Simplest Form:  
-5/6
+
1/6
=
-2/3
Note:  
-5/6
+
1/6
=
1/6
5/6
