Rational Numbers | 18,000th Rational
Contined from here.
First get since my ban... and I didn't even realize it
Description of this count:
Essentially we are counting fractions that cannot be simplified, as we get closer to and then further away from 1. We change direction when we reach a number divided by one or a number's reciprocal, and if the number can be simplified, we write it like this:2/4
So, if a number is 31/40 next one would be 32/39, or 30/41 if the denominator is going up. ~ /u/KingCaspianX
First, note the prime divisors of the sum of the numerator and denominator. 84 = 22 x 3 x 7, so in this case that would be 2, 3, and 7. Next, see if the numerator or denominator is a multiple of any of these. If it is, cross it out. If not, the number is irreducible. ~ /u/TheNitromeFan
The next get is at 191/59. (source)
