To calculate $$ 7 \tan 18^{\circ} $$ and round it to one decimal place:

1. **Find the tangent of 18 degrees:**
   $$
   \tan(18^{\circ}) \approx 0.3249
   $$

2. **Multiply by 7:**
   $$
   7 \times 0.3249 \approx 2.2743
   $$

3. **Round to one decimal place:**
   $$
   2.2743 \approx 2.3
   $$

**Final Answer:** $$ 2.3 $$
$$ 7 \tan 18^{\circ} \approx 2.3 $$
