Puzzle solved
If assumed all octal numbers, numerator converted back to decimal:

22/7 - 6/4745 = 104348/33215 = 3.141592654 (10 digits, rounded)

This value happened to be one of Pi convergents, from continued fraction terms: [3;7,15,1,292,1]
Thus, all is needed is to "remove" the denominator, by changing exponent to 0/4

Exactly, congrats!

Perhaps I should have chosen a higher base to make it a bit more difficult to check :-)
