To find the ratio of the side opposite \( \angle A \) to the hypotenuse of triangle \( ABC \):

1. In triangle \( ABC \):
- \( AB = 9 \) is opposite \( \angle C \)
- \( BC = 12 \) is opposite \( \angle A \)
- \( AC = 15 \) is the hypotenuse

The opposite side to \( \angle A \) is \( BC = 12 \).

2. The hypotenuse is \( AC = 15 \).

Now, we can find the ratio of the opposite side to the hypotenuse:

\[
\text{Ratio} = \frac{\text{opposite side}}{\text{hypotenuse}} = \frac{12}{15} = \frac{4}{5} = 0.8
\]

Next, we need to identify the location of point \( A' \) in triangle \( A'B'C' \):

In triangle \( A'B'C' \):
- The side lengths are 30, 24, and 18.
- The largest side is the hypotenuse, which is 30.

The side lengths:
- Let the side opposite \( A' \) be \( B'C' = 18 \) (as it's opposite to the angle \( A' \)).
- The side opposite \( B' \) is \( A'C' = 24 \).

Since we found that the ratio of the opposite side to the hypotenuse is \( 0.8 \), which corresponds to the side opposite \( A \) as \( BC = 12 \) and hypotenuse \( AC = 15 \) in triangle \( ABC \).

In triangle \( A'B'C' \), since point \( A' \) corresponds to the angle opposite side \( B'C' = 18 \), the correct response is:

**The ratio of the opposite side to the hypotenuse is 0.8, and point \( A' \) is opposite the side that has length 18.**
