Sum of  

3/4

and

1/5

in Simplest Form

Given:   +
Since the denominators are not common (not the same), we need to find the Least Common Denominator (LCD), which is equivalent to the Least Common Multiple of 4 and 5:
LCD = LCM(4, 5) = 20
Express the given fractions as equivalent fractions with respect to the LCD (20):
=   and   = As a result,   + = +
Since the equivalent fractions have common denominators, we can add the numerators:
+ = = is in Simplest Form since the Greatest Common Factor of 19 and 20 equals 1, GCF(19, 20) = 1Therefore, the Sum of  

3/4

and

1/5

is equal to

19/20

in Simplest Form:  

3/4

+

1/5

=

19/20
