Sum of  

19/15

and

1/4

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 15:
LCD = LCM(4, 15) = 60
Express the given fractions as equivalent fractions with respect to the LCD (60):
=   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 60 and 91 equals 1, GCF(60, 91) = 1Therefore, the Sum of  

19/15

and

1/4

is equal to

91/60

in Simplest Form:  

19/15

+

1/4

=

91/60

Note: is an improper fraction, and as a mixed number,   = 1
