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?(1 point)

To find out how long it will take Stacy to paint the entire room, we first determine her painting rate.

Stacy can paint \( \frac{3}{4} \) of the bedroom in 3 hours.

To find out how long it takes her to paint 1 whole bedroom, we set up a proportion:

\[
\text{Time to paint 1 room} = \frac{3 \text{ hours}}{\frac{3}{4} \text{ room}} = \frac{3}{\frac{3}{4}} = 3 \times \frac{4}{3} = 4 \text{ hours}
\]

Thus, it takes her 4 hours to paint the entire bedroom.

Therefore, the correct response is:

4 hours.
