Final answer:

The true proportion is 54:9 = 6:3.


Step-by-step explanation:

The statement that expresses a true proportion is A. 54:9 = 6:3. To determine if two ratios are proportional, we can simplify them and see if they are equal. In this case, we can simplify the ratio on the left side to 6:1 and the ratio on the right side to 2:1. Since they are both equal, the proportion is true.
