Certainly! Let's solve the problem step-by-step.

**Problem:**
A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle?

**Solution:**

1. **Understand the Given Information:**
   - **Ratio of students owning a bicycle:** 4 out of 5.
   - **Total number of students in the school:** 800.

2. **Set Up the Proportion:**
   The ratio can be expressed as:
   $$
   \frac{4}{5} = \frac{\text{Number of students owning bicycles}}{800}
   $$

3. **Let’s Call the Number of Students Owning Bicycles as $$ x $$:**
   $$
   \frac{4}{5} = \frac{x}{800}
   $$

4. **Solve for $$ x $$:**
   Cross-multiply to solve for $$ x $$:
   $$
   5 \times x = 4 \times 800
   $$
   $$
   5x = 3200
   $$
   $$
   x = \frac{3200}{5}
   $$
   $$
   x = 640
   $$

5. **Conclusion:**
   - **Number of students owning a bicycle:** 640

**Answer:** 640 students out of the 800 own a bicycle.
640 students own a bicycle.
