Sum of  
13/8
and
39/8
in Simplest Form

Given:  
13/8
+
39/8

Since the denominators are common (the same), we can add the numerators:
13/8
+
39/8
=
13 + 39/8
=
52/8
However,  
52/8
 is NOT in Simplest Form since the Greatest Common Factor of 8 and 52 does not equal 1, GCF(8, 52) ≠ 1
Upon inspection, the GCF(8, 52) = 4
In Simplest Form,  
52/8
=
52 ÷ 4/8 ÷ 4
=
13/2
 (1 is the only factor common to 13 and 2)
Therefore, the Sum of  
13/8
and
39/8
is equal to
13/2
in Simplest Form:  
13/8
+
39/8
=
13/2

Note:
13/2
is an improper fraction, and as a mixed number,  
13/2
= 6
1/2
