To order the heights from greatest to least using inequality symbols, we compare the heights of Ralph (68 inches), Abdul (73 inches), Marshall (65 inches), and Francesco (70 inches).
Abdul is the tallest at 73 inches, so we start with him.
Next, we have Francesco at 70 inches, followed by Ralph at 68 inches, and finally Marshall at 65 inches.
The correct order from greatest to least is:
73 > 70 > 68 > 65
So the response would be:
73 > 70 > 68 > 65. Abdul is tallest.
