Answer

To determine which decimal number is not equivalent to 5.7, we will analyze each option based on the rules of decimal representation.

### Step-by-Step Solution:

1. **Understanding Decimal Equivalence**:
- When zeros are added to the right of a decimal number, they do not change the value of that number. For example, 5.7 is the same as 5.70, 5.700, or 5.7000.

2. **Analyzing the Options**:
- **Option 1: 5.70**
- This has a zero after the 7. According to the rule, this is equivalent to 5.7.
- **Option 2: 5.07**
- This has a zero before the 7. This means it represents a different value. 5.07 is actually 5 + 0.07, which is 5.07, not equivalent to 5.7.
- **Option 3: 5.700**
- This has two zeros after the 7. According to the rule, this is equivalent to 5.7.
- **Option 4: 5.7000**
- This has three zeros after the 7. According to the rule, this is equivalent to 5.7.

3. **Conclusion**:
- The only option that is not equivalent to 5.7 is **5.07**.

### Final Answer:
The decimal number not equivalent to 5.7 is **5.07**.
