Atacy is painting her bedroom. She is able to paint 3/4 of the bedroom in 3 hours. At this rate, how long will it take hwr to paint the entire room?
If Atacy is able to paint 3/4 of the bedroom in 3 hours, then she paints 1/4 of the bedroom in 3/4 * 3 = 9/4 hours.
Therefore, it will take her 9/4 hours * 4 = <<9/4*4=9>>9 hours to paint the entire room. Answer: \boxed{9}.
To find out how long it will take Atacy to paint the entire bedroom, we can set up a proportion.
Let's assign the variable "x" to represent the time it will take Atacy to paint the entire room.
We know that Atacy can paint 3/4 of the bedroom in 3 hours. Therefore, the proportion can be set up as:
3/4 = x/1 (since painting the entire room is equivalent to 1)
To solve for x, we can cross multiply:
4 * x = 3 * 1
4x = 3
Now, we can solve for x by dividing both sides of the equation by 4:
x = 3/4
So, it will take Atacy 3/4 of an hour (or 45 minutes) to paint the entire room.
To find out how long it will take Atacy to paint the entire room, we need to determine the time it takes her to paint 1/4 of the room since she can currently paint 3/4 of the bedroom in 3 hours.
To calculate the time it takes to paint 1/4 of the room, we can divide the time it takes to paint 3/4 of the room by 3.
3/4 of the room = 3 hours
1/4 of the room = (3 hours) / 3 = 1 hour
So, it takes Atacy 1 hour to paint 1/4 of the room.
Therefore, it will take Atacy 4 hours to paint the entire room.
