were p and q are two integers.
3.72727272… = 4 / 11
So 3.72727272... is rational number.
0.073303330... is not rational number because:
0.073303330330330... =
7330 / 100000 + 30333 / 10000000000 + 33033/100000000000000 +...=
7330 / 10⁵ + 30333 / 10¹⁰ + 30333 / 10¹⁰ + 30333 / 10¹⁴ +...
We need to divide 30333 by some exponent of 10 an infinite number of times.
So 0.073303330... is irrational number
