Let's classify each number as rational or irrational:

  1. -15: Rational (It can be expressed as a fraction, for example, -15/1.)
  2. 3.67: Rational (It can be expressed as 367/100.)
  3. √25: Rational (Since √25 = 5, which is an integer.)
  4. : Irrational (π is an irrational number, and multiplying it by 2 does not result in a rational number.)
  5. 4.8: Rational (It can be expressed as 48/10 or 24/5, which are both fractions.)
  6. √12: Irrational (Since √12 can be simplified to 2√3, and √3 is irrational.)

So the classifications are:

  • Rational: -15, 3.67, √25, 4.8
  • Irrational: 2π, √12
