Answer:
1/9
Step-by-step explanation:
We have been given that
The part of room cleaned by me = 6/9
and the part of the room cleaned by friend = 2/9
Hence, total area of the room cleaned is given by
[tex]\frac{6}{9}+\frac{2}{9}\\\\=\frac{8}{9}[/tex]
Therefore, we still have to clean below amount
[tex]1-\frac{8}{9}\\\\=\frac{1}{9}[/tex]
