Is 19 a multiple of 3? Classify using a whole-number multiplier.
- Test the candidate by division: 19÷3 has quotient 6, remainder 1.
- The zero-remainder requirement is not met, so this is not a multiple.
Answer: Non-example — dividing 19 by 3 gives quotient 6 and remainder 1; a multiple has zero remainder.
