Rational numbers are defined as numbers that can be expressed as the quotient of two integers, where the denominator is not zero. Based on this definition, the following examples from your list are rational numbers:

• 3 (can be expressed as 3/1)
• 1/3 (already in fractional form)
• 21/5 (already in fractional form)
• -3 (can be expressed as -3/1)
