Let's solve each part step by step.

### Problem Analysis
The question asks us to either increase or decrease the number \( 3 \) by a specified percentage. Here’s how we can approach each part:

### Solution Steps

1. **3 increased by 250%**:
   - To increase a number by 250%, we calculate:
     \[
     3 + \left(3 \times \frac{250}{100}\right) = 3 + (3 \times 2.5) = 3 + 7.5 = 10.5
     \]
   - **Answer**: \( 10.5 \)

2. **3 decreased by 100%**:
   - To decrease a number by 100%, we subtract 100% of 3 from 3:
     \[
     3 - \left(3 \times \frac{100}{100}\right) = 3 - 3 = 0
     \]
   - **Answer**: \( 0 \)

3. **3 decreased by 150%**:
   - To decrease a number by 150%, we subtract 150% of 3 from 3:
     \[
     3 - \left(3 \times \frac{150}{100}\right) = 3 - (3 \times 1.5) = 3 - 4.5 = -1.5
     \]
   - **Answer**: \( -1.5 \)

### Final Answers
- **3 increased by 250% is**: \( 10.5 \)
- **3 decreased by 100% is**: \( 0 \)
- **3 decreased by 150% is**: \( -1.5 \)
