    let's say \[\frac{ 2 }{ 4 } and \frac{ 22 }{ 7 }\] now we can see that value of 2/4 =0.5 which ends and terminates at 0.5 after division but 22/7 = 3.14285.......it doesn't end at all so 22/7 is irrational and 2/4 is rational clear? irrational means which never terminates or never ends after numerous division
