Answer 1

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.
