Which of the following is a correct formal expression of the division property of equality?

• A. The division property states that if a = b, then a + c = b + c for any c.
• B. If a/c = b/c, then a = b for any c, including c = 0.
• C. If a = b, then ac = bc only when c = 0.
• D. If a = b and c ≠ 0, then a/c = b/c.

Answer: (D)
