The exercise asks to arrange the numbers in descending order. Here's a list of the numbers:

1. \( 3.05 \)
2. \( 1.5 \)
3. \( 1 \)
4. \( \sqrt{7} \)
5. \( -4.32 \)
6. \( -\sqrt{8} \)

Let's first evaluate the approximate values of the square roots:
- \( \sqrt{7} \approx 2.65 \)
- \( \sqrt{8} \approx 2.83 \)

Now we have the numbers as:
- \( 3.05 \)
- \( 1.5 \)
- \( 1 \)
- \( 2.65 \) (which is \( \sqrt{7} \))
- \( -4.32 \)
- \( -2.83 \) (which is \( -\sqrt{8} \))

Now, we arrange these values in descending order:
- \( 3.05 \)
- \( 2.65 \) ( \( \sqrt{7} \) )
- \( 1.5 \)
- \( 1 \)
- \( -2.83 \) ( \( -\sqrt{8} \) )
- \( -4.32 \)

The answer is:
**Order (from largest to smallest):** \( 3.05, \sqrt{7}, 1.5, 1, -\sqrt{8}, -4.32 \).

Here are 5 related questions for practice:
1. Arrange \( \sqrt{2}, \sqrt{5}, 2.5, -1, -\sqrt{3} \) in descending order.
2. Simplify and compare \( \sqrt{3} \) and \( \sqrt{8} \).
3. Calculate the exact decimal approximation of \( \sqrt{11} \).
4. How do square roots of non-perfect squares behave in comparison to integers?
5. Compare \( \sqrt{9.5} \) and \( 3.2 \).

**Tip:** When comparing square roots, it's often useful to approximate their decimal values first!
