Sum of  

4/20

and

4/20

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 8 and 20 does not equal 1, GCF(8, 20) ≠ 1
Upon inspection, the GCF(8, 20) = 4In Simplest Form,   = =  (1 is the only factor common to 2 and 5)Therefore, the Sum of  

4/20

and

4/20

is equal to

2/5

in Simplest Form:  

4/20

+

4/20

=

2/5
