Why (22/7) is a rational number and (π) is irrational number. please explain.
Edit: How can you say that $22/7=\pi$, when one number if rational and the other is irrational?

My guess is that you are thinking of the approximation $22/7 \approx \pi$. The two numbers $\pi$ and $22/7$ are not equal, so there's no contradiction in one being rational and the other irrational.
Sometimes you use $22/7$ as a number "fairly close" to $\pi$, but:
$$\pi = 3.14159265...$$ while $$22/7 = 3.14285714...$$
