Stacy is able to paint 3/4 of the bedroom in 3 hours. To find out how long it will take her to paint the entire room, we need to determine the time it takes to paint 1/4 of the bedroom.
Since Stacy painted 3/4 of the room in 3 hours, she painted 1/4 of the room in 3/4 * 3 = 9/4 hours.
Therefore, it will take Stacy 9/4 hours or 2.25 hours to paint the entire room.
So the answer is 9/4 hours.
