Sum of  

-5/6

and

1/6

in Simplest Form

Given:   +
Since the denominators are common (the same), we can add the numerators:
+ = = However,    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) = 2In Simplest Form,   = =  (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:   + = −
