Answer
The scale factor is \(\frac{1}{6}\).
Solution
To find the scale factor of the drawing, we need to compare the width of the pool table in the drawing to the actual width of the pool table.
1. **Convert the actual width to the same unit as the drawing:**
- The actual width of the pool table is 3 feet. Since there are 12 inches in a foot, we convert feet to inches:
\[
3 \text{ feet} = 3 \times 12 \text{ inches} = 36 \text{ inches}
\]
2. **Set up the scale factor:**
- The scale factor is the ratio of the width in the drawing to the actual width:
\[
\text{Scale Factor} = \frac{\text{Width in Drawing}}{\text{Actual Width}} = \frac{6 \text{ inches}}{36 \text{ inches}}
\]
3. **Simplify the fraction:**
- We can simplify \(\frac{6}{36}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 6:
\[
\frac{6 \div 6}{36 \div 6} = \frac{1}{6}
\]
Thus, the scale factor used in the drawing is \(\frac{1}{6}\).

Bonus Knowledge
To find the scale factor, we need to compare the width of the pool table in the drawing to its actual width. The drawing shows the pool table as 6 inches wide, while the actual table is 3 feet wide. First, we need to convert 3 feet to inches: 3 feet × 12 inches/foot = 36 inches. Now, we calculate the scale factor as the drawing width divided by the actual width. Scale factor = Drawing width / Actual width = 6 inches / 36 inches = 1/6. So, the scale factor used in the drawing is 1/6.
