Sum of  
1/5
and
2/3
in Simplest Form

Given:  
1/5
+
2/3

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 3 and 5:
LCD = LCM(3, 5) = 15
Express the given fractions as equivalent fractions with respect to the LCD (15):
1/5
=
3/15
  and  
2/3
=
10/15
As a result,  
1/5
+
2/3
=
3/15
+
10/15

Since the equivalent fractions have common denominators, we can add the numerators:
3/15
+
10/15
=
3 + 10/15
=
13/15
13/15
is in Simplest Form since the Greatest Common Factor of 13 and 15 equals 1, GCF(13, 15) = 1
Therefore, the Sum of  
1/5
and
2/3
is equal to
13/15
in Simplest Form:  
1/5
+
2/3
=
13/15
