Stacy’s painting her bedroom she is able to paint 3/4 of the bedroom in three hours. At this rate. How long will it take her to paint the entire room?
If Stacy is able to paint 3/4 of the bedroom in three hours, it means she paints 3/4 * 1 = <<3/4*1=0.75>>0.75 of the bedroom per hour.
Therefore, it will take her 1 / 0.75 = <<1/0.75=1.3333333333333333>>1.33 hours to paint the entire room. Answer: \boxed{1.33}.
