To determine how many out of 700 people on the subway do **not** have a briefcase, follow these steps:

1. **Understand the Ratio:**
   - **Given:** 8 out of every 11 people carry a briefcase.
   - **Therefore:** 11 - 8 = 3 out of every 11 people **do not** carry a briefcase.

2. **Set Up the Proportion:**
   $$
   \frac{3}{11} = \frac{x}{700}
   $$
   Where $$ x $$ is the number of people without a briefcase.

3. **Solve for $$ x $$:**
   $$
   x = \frac{3}{11} \times 700
   $$
   $$
   x = \frac{2100}{11}
   $$
   $$
   x \approx 190.91
   $$

4. **Round Appropriately:**
   Since you can't have a fraction of a person, round to the nearest whole number.
   $$
   x \approx 191
   $$

**Conclusion:**  
Approximately **191** people out of 700 on the subway do not have a briefcase.
About 191 people out of 700 do not have a briefcase.
