On real numbers, (aRb) is defined when (|a|\ge |b|). Is this relation transitive?

Answer and explanation

Correct answer: Yes, because (|a|\ge |b|) and (|b|\ge |c|) imply (|a|\ge |c|)

Step 1: The relation compares absolute values of numbers. Step 2: If (|a|\ge |b|) and (|b|\ge |c|), then by the usual order (|a|\ge |c|), so (aRc). Step 3: Treat absolute value as the compared quantity and apply the order rule.
