Let's break down the problem step by step.

- Total people surveyed = 160
- 3/4 of those asked own a dog or cat.
- 15% do not own a pet at all.
- The remaining people are fish owners.

### Step-by-Step Calculation:

1. **People who own a dog or cat:**
   \( \frac{3}{4} \) of 160:
   \[
   \frac{3}{4} \times 160 = 120 \text{ people}
   \]

2. **People who do not own any pets:**
   15% of 160:
   \[
   0.15 \times 160 = 24 \text{ people}
   \]

3. **Fish owners:**
   The remaining people will be the fish owners. So, subtract the number of dog/cat owners and non-pet owners from the total:
   \[
   160 - 120 - 24 = 16 \text{ fish owners}
   \]

Thus, there are **16 fish owners**.

5. How many people are not fish owners?

### Tip:
Always check if all percentages and fractions are accounted for when solving survey-based problems to avoid missing groups!

People were asked if they own a pet. 3/4 of those asked own a dog or cat. 15% do not own a pet at all. The remaining people asked were fish owners. If they polled 160 people, how many fish owners are there?
