Final answer:
The correct reason for the statement is the Property of reciprocals.
Step-by-step explanation:
The correct reason for the statement "if a/c = b/c and c ≠ 0, then a = b" is 2) Property of reciprocals.
To understand why, we can cross-multiply the equation a/c = b/c. This gives us ac = bc. Since c ≠ 0, we can divide both sides of the equation by c to get a = b. This shows that if the fractions a/c and b/c are equal, then the original numbers a and b will also be equal.
