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, it means she paints 1/4 of the bedroom in 1 hour.
Therefore, it will take her 4 hours to paint the entire room. Answer: \boxed{4}.
To find out how long it will take Stacy to paint the entire room, we can set up a proportion based on the rate at which she is painting.
Stacy is able to paint 3/4 of the bedroom in 3 hours. Let's set this up as a proportion:
(3/4) bedroom / 3 hours = 1 bedroom / x hours
To solve for x (the time it will take to paint the entire room), we can cross multiply:
(3/4) bedroom * x hours = 1 bedroom * 3 hours
Now we can solve for x:
(3/4) * x = 3
Simplifying the left side, we get:
3x/4 = 3
To get rid of the fraction, we can multiply both sides by 4:
4 * (3x/4) = 4 * 3
3x = 12
Finally, to solve for x, we divide both sides by 3:
x = 12 / 3
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 her painting rate.
We are given that Stacy can paint 3/4 of the bedroom in 3 hours. Let's denote the time it will take her to paint the entire room as "x" hours.
The proportion we can set up is:
(3/4) / 3 = 1 / x
To solve for x, we can cross-multiply:
(3/4) * x = 3 * 1
Simplifying the equation:
3x/4 = 3
Now, we can solve for x by multiplying both sides by 4/3:
x = (4/3) * 3
x = 4
Therefore, it will take Stacy 4 hours to paint the entire room.
