Stacy 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 her to paint the entire room?
6 hours
12 hours
9/4 hours
4 hours
If Stacy is able to paint 3/4 of the bedroom in 3 hours, then she will take 4*(3/4) = <<4*(3/4)=3>>3 hours to paint the entire room. Answer: \boxed{3}.
To find out how long it will take Stacy to paint the entire room, we can set up a proportion using the information given.
Let's set up the proportion:
(3/4) / 3 = 1 / x
Cross-multiply the proportion:
(3/4) * x = 3 * 1
Multiply 3/4 by x:
3x/4 = 3
Multiply both sides of the equation by 4 to get rid of the fraction:
3x = 4 * 3
Simplify the equation:
3x = 12
Divide both sides of the equation by 3:
x = 12 / 3
Simplify:
x = 4
Therefore, it will take Stacy 4 hours to paint the entire room.
To find out how long it will take Stacy to paint the entire room, we can set up a proportion based on the amount of time it takes her to paint a certain fraction of the room.
Given that Stacy can paint 3/4 of the bedroom in 3 hours, we can set up the following proportion:
(3/4) / 3 = 1 / x
To solve for x, we can cross-multiply:
(3/4) * x = 3 * 1
3x = 4 * 3
3x = 12
Now, divide both sides of the equation by 3:
x = 12 / 3
x = 4
Therefore, it will take Stacy 4 hours to paint the entire room.
The correct answer is 4 hours.
