Irrational numbers is defined as something that cannot be expressed as a fraction .
Now I got a question . So is "120%" an integer or irrational number ?
Do I take 120% as 1.2 or just 120% as an integer (ignoring the % sign)

1What does it have to do with irrationals anyway? – Vim Jun 19 '16 at 14:41

$%$ just means $1/100$. – egreg Jun 19 '16 at 15:14

$120\%$ means a scalar factor of ${6\over5}\in{\mathbb Q}$ when applied to real quantities, or quantities referred to a unit, like dollars. But nobody would declare that the solution of the equation $5x-6=0$ is $120\%$.
