Answer 1

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

Stacy paints \( \frac{3}{4} \) of the room in 3 hours. To find out how long it takes to paint the entire room, we can set up a proportion.

If \( \frac{3}{4} \) of the room takes 3 hours, then 1 whole room would take \( x \) hours, which can be calculated as follows:

\[
\frac{3}{4} \text{ room} = 3 \text{ hours}
\]
\[
1 \text{ room} = x \text{ hours}
\]

Setting up the ratio:

\[
\frac{3}{4} : 3 = 1 : x
\]

Cross multiplying gives us:

\[
3x = 4 \cdot 3
\]
\[
3x = 12
\]
\[
x = \frac{12}{3} = 4
\]

Thus, it takes Stacy 4 hours to paint the entire room. Therefore, the answer is:

**4 hours**
