Explanation

To determine the number of significant figures in the numbers 6.320, 6.032, and 0.0006032, we will follow the rules of significant figures step by step.

### Step-by-Step Solution:

1. **Identify the first number: 6.320**
- The digits are 6, 3, 2, and 0.
- All non-zero digits (6, 3, and 2) are significant.
- The zero after the decimal point (0) is also significant because it follows a non-zero digit.
- **Total significant figures = 4.**

2. **Identify the second number: 6.032**
- The digits are 6, 0, 3, and 2.
- Again, all non-zero digits (6, 3, and 2) are significant.
- The zero between 6 and 3 is significant because it is between two non-zero digits.
- **Total significant figures = 4.**

3. **Identify the third number: 0.0006032**
- The digits are 0, 0, 0, 0, 6, 0, 3, and 2.
- The leading zeros (0.000) are not significant; they only indicate the position of the decimal point.
- The digits 6, 0, 3, and 2 are significant.
- The zero between 6 and 3 is significant.
- **Total significant figures = 4.**

### Final Answer:
The respective number of significant figures for the numbers 6.320, 6.032, and 0.0006032 are: **4, 4, 4.**
