science cannot really express the earth as a percentage because the universe is ever expanding, while the earth is constant. Even as you finish reading this sentence, the universe has grown bigger than what it was when you started reading

I very much regret that the exact percentage is not known since no one has managed to find a way to find the exact mass of the earth's crust, which would probably form the denominator of such a percentage.

pi is a universal constant. It is a transcendental number which is a special kind of irrational number. It cannot be expressed as a terminating or repeating decimal, nor as a ratio of integers or surds. There are various ways in which pi can be calculated and expressed. Commonly used approximations are 22/7, 3.14, 3.14159. Last year pi was calculated to 5 trillion digits although 40 digits are thought to be sufficient to calculate the angle subtended on earth by a hydrogen atom at the far end of the known universe!

A number that cannot be expressed as the ratio of two integers is known as an irrational number.

One of the largest is called Graham's Number, which has so many digits that it can only be expressed as "powers of powers of powers". The last ten digits of Graham's number are ...2464195387. But the observable universe is too small to contain a written representation of the whole number, even if the digits were of subatomic size. It is many orders of magnitude greater than the number of elementary particles in the known universe.

That is un known.

Roughly about 20%-40% of the observable universe is blocked from Earth's view by the Milky Way and other objects including galaxies. This is because the Milky Way galaxy itself occupies a significant portion of our observable sky, obstructing our view of distant regions of the cosmos.
