Sum of  
7/9
and
2/3
in Simplest Form

Given:  
7/9
+
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 9:
LCD = LCM(3, 9) = 9
Express the given fractions as equivalent fractions with respect to the LCD (9):
7/9
=
7/9
  and  
2/3
=
6/9
As a result,  
7/9
+
2/3
=
7/9
+
6/9

Since the equivalent fractions have common denominators, we can add the numerators:
7/9
+
6/9
=
7 + 6/9
=
13/9
13/9
is in Simplest Form since the Greatest Common Factor of 9 and 13 equals 1, GCF(9, 13) = 1
Therefore, the Sum of  
7/9
and
2/3
is equal to
13/9
in Simplest Form:  
7/9
+
2/3
=
13/9
Note:
13/9
is an improper fraction, and as a mixed number,  
13/9
= 1
4/9
