Here's the classification of the given numbers into rational and irrational categories:
Rational Numbers:
- 121212 (an integer)
- 848484 (an integer)
- \( 36\sqrt{36} \) (This is equal to \( 36 \times 6 = 216 \), which is also an integer)
- \( 0.56\overline{0} \) (a repeating decimal, which can be expressed as a fraction)
- \( -\frac{7}{19} \) (a fraction)
Irrational Numbers:
- \( \pi \) (an irrational constant)
- \( 19\sqrt{19} \) (this cannot be simplified to a rational number)
So, the final sorting would be:
Rational Numbers:
- 121212
- 848484
- \( 36\sqrt{36} \)
- \( 0.56\overline{0} \)
- \( -\frac{7}{19} \)
Irrational Numbers:
- \( \pi \)
- \( 19\sqrt{19} \)
