Answer:
9 is the least common denominator for the given equation
Step-by-step explanation:
Given equation is StartFraction 2 Over 9 EndFraction x + two-thirds x = 7.
It can be written as [tex]\frac{2}{9}x+\frac{2}{3}x=7[/tex]
To find the least common denominator for the given equation :
That is to find the Least common Multiple of the denominators.
[tex]\frac{2}{9}x+\frac{2}{3}x=7[/tex]
[tex]\frac{2x+2x(3)}{9}=7[/tex] ( here LCM of 9 and 3 is 9 so we take 9 as LCM )
Therefore 9 is the least common denominator for the given equation
Answer: the answer is 9
