Sum of  
3/15
and
6/15
in Simplest Form

Given:  
3/15
+
6/15

Since the denominators are common (the same), we can add the numerators:
3/15
+
6/15
=
3 + 6/15
=
9/15
However,  
9/15
 is NOT in Simplest Form since the Greatest Common Factor of 9 and 15 does not equal 1, GCF(9, 15) ≠ 1
Upon inspection, the GCF(9, 15) = 3
In Simplest Form,  
9/15
=
9 ÷ 3/15 ÷ 3
=
3/5
 (1 is the only factor common to 3 and 5)
Therefore, the Sum of  
3/15
and
6/15
is equal to
3/5
in Simplest Form:  
3/15
+
6/15
=
3/5
