Amanda can paint the room by herself in 8 hours. Therefore, she can paint (frac{1}{8}) of the room in an hour. In the same way, Dani can paint (frac{1}{x}) of the room in an hour. Together, they can paint (frac{1}{6}) part of the room in an hour. Now, write the equation and solve for x.
(frac{1}{8}+frac{1}{x}=frac{1}{6}⇒frac{1}{6}-frac{1}{8}=frac{1}{24}⇒x=24)
Dani can paint the room in 24 hours. Then, in six hours, Dani paints (frac{6}{24}) or (frac{1}{4}) part or 25% of the room.
