Question

4,03132 es un numero racional o irracional

Answer 1

The number 8 is a rational number because it can be written as the fraction 8/1.
Likewise, 3/4 is a rational number because it can be written as a fraction.
Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
But π and √2 are irrational, as these can't be written in fraction.
