Respuesta :
the LCD of the two is 9 what you do is this so 1/3,2/9 is simple its 1/3 2/3 1 then lets try the 2/9 2/9 4/9 6/9 and keep doing that until they both reach the SAME number.
The LCD (Least common denominator) is 9,
For the denominators (3, 9) the least common multiple (LCM) is 9.
Therefore, the least common denominator (LCD) is 9.
Hope This Helps :D
