Stacy is painting her bedroom. She is able to paint 3/4 of the bedroom in 3 hours. At this rate, how long willit take her to
paint the entire room? (1 point)
To find out how long it will take Stacy to paint the entire room, we can use the concept of proportions.
If Stacy is able to paint 3/4 of the room in 3 hours, then we can set up the following proportion:
(3/4) room / 3 hours = (1) room / x hours
To find the value of x (the time it will take Stacy to paint the entire room), we can cross multiply:
(3/4) room * x hours = (1) room * 3 hours
Multiplying the fractions, we get:
(3x/4) hours = 3 hours
To isolate x (the time it will take Stacy), we can divide both sides of the equation by (3/4) hours:
x = (3 hours) / (3/4) hours
Dividing, we get:
x = 4 hours
Therefore, it will take Stacy 4 hours to paint the entire room.
