Why is this not 0 on 50g or Prime?

In my little thinking bubble (inf/inf) would be 1. All this naturally arises from the nature of infinity and also the inverse of it as zero(, which would lead to something odd like 1/Real as a fraction, known as irrational numbers algebraic fraction, another blu tack of math, since by first defined rules of fraction such shouldn't exist) both have properties of numbers and symbolic operators in academic view of mathematics. Which my little game (which started btw. when the limits and infinity were force-fed to me long way back.) doesn't try to challenge, it just holds true in another dimension.
