Examine the list below.
55 percent sign comma space minus 23 comma space 2 over 3 comma space left parenthesis 58 space cross times space 10 squared right parenthesis comma space 7.5

Which answer choice shows the list in order from greatest to least?
A.left parenthesis 58 cross times 10 squared right parenthesis comma space 7.5 comma space 2 over 3 comma space 55 percent sign comma space minus 23
B.negative 23 comma space 55 percent sign comma space 2 over 3 comma space 7.5 comma space left parenthesis 58 cross times 10 squared right parenthesis
C.2 over 3 comma space 7.5 comma space minus 23 comma space 55 percent sign comma space left parenthesis 58 cross times 10 squared right parenthesis

Let's evaluate the numbers in the list before ordering them:

1. **\( 55\% \)** is 0.55.
2. **\( -23 \)** is a negative integer, -23.
3. **\( \frac{2}{3} \)** is approximately 0.6667.
4. **\( 58 \times 10^2 \)** is 5800.
5. **7.5** is a positive decimal, 7.5.

Now, let's order them from **greatest to least**:

- \( 5800 \) is the largest.
- \( 7.5 \) is next.
- \( \frac{2}{3} \) or 0.6667 follows.
- \( 55\% \) or 0.55 comes after that.
- \( -23 \) is the smallest value.

Thus, the correct order from **greatest to least** is:
\[
5800, 7.5, \frac{2}{3}, 55\%, -23
\]

This matches **Answer A**.

### Final Answer: **A**.
