      Fun fact: decimal representations of sevenths follow a repeating pattern of the same 6 digits in the same order, from a different starting point:

      1/7: 0.142857142857…
      2/7: 0.285714285714…
      3/7: 0.428571…
      4/7: 0.571428…
      5/7: 0.714285…
      6/7: 0.857142…

      Something similar happens with 13ths, but there are two different sets of six repeating digits, with 1, 3, 4, 9, 10, and 12 (thirteenths) using one set of digits (769230) and 2, 5, 6, 7, 8, and 11 using the other (153846). Note the mirrored pattern of numerators here: 1_34______9A_C (using hex-like letters to represent digits over 9) and _2__5678__B_. There’s probably a great reason for that but it hasn’t occurred to me, and I’ve never looked it up.

      I also greatly enjoy that this happens with the two numbers most associated with luck, 7 and 13.

      Took me way too long to realize you meant the complement of 6/7 as in 6/7 + 1/7 = 1
