6 hours 12 hours 9/4 hours 4 hours
(PICK ONE OF THESE ANSWERS)
To paint 3/4 of the bedroom in 3 hours, Stacy completes 3/4 * 3 = 9/4 of the bedroom in 3 hours.
So, at this rate, it would take Stacy 9/4 hours to paint the entire room.
Therefore, the correct answer is 9/4 hours.
To determine how long it will take Stacy to paint the entire room, we can set up a proportion using the given information:
3/4 of the room = 3 hours
Let x be the time it takes to paint the entire room.
We can set up the proportion:
(3/4) / 3 = (1) / x
Cross-multiplying, we have:
3x = 4 * 3
3x = 12
x = 12 / 3
x = 4
Therefore, it will take Stacy 4 hours to paint the entire room.
The correct answer is 4 hours.
To find out how long it will take Stacy to paint the entire room, we can use the information provided.
We know that Stacy can paint 3/4 of the bedroom in 3 hours. Therefore, in 1 hour, she can paint 3/4 divided by 3, which equals 1/4 of the bedroom.
To find the total time it will take for her to paint the entire room (4/4 or 1), we need to divide 1 by the fraction that represents how much she can paint in one hour (1/4).
Dividing 1 by 1/4 can be done by multiplying 1 by the reciprocal of 1/4, which is 4/1.
So, the answer is 1 hour multiplied by 4/1 gives us 4 hours. Therefore, it will take Stacy 4 hours to paint the entire room.
