Sum of  

2/9

and

1/9

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 3 and 9 does not equal 1, GCF(3, 9) ≠ 1
Upon inspection, the GCF(3, 9) = 3In Simplest Form,   = =  (1 is the only factor common to 1 and 3)Therefore, the Sum of  

2/9

and

1/9

is equal to

1/3

in Simplest Form:  

2/9

+

1/9

=

1/3
