Sum of  

14/20

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 18 and 20 does not equal 1, GCF(18, 20) ≠ 1
Upon inspection, the GCF(18, 20) = 2In Simplest Form,   = =  (1 is the only factor common to 9 and 10)Therefore, the Sum of  

14/20

and

4/20

is equal to

9/10

in Simplest Form:  

14/20

+

4/20

=

9/10
