Is 50 an irrational number?
No. An irrational number isn't a whole number, nor can it be represented exactly as a fraction of two whole numbers. 50 is a whole number, so it's rational. 50/3, while having a repeating decimal, is still rational because it's an exact fraction. The square root of two is irrational because there is no fraction that can exactly represent it. The same goes for pi (although 22/7 is close enough for government work -- jk).
