number × 4/6 = 1/9 → number = 1/9 ÷ 4/6 = 1/9 × 6/4 = (1×6)/(9×4) = 6/36 = 1/6

9 occurs more than any other number, so it is the mode.

First, it is going by ones: 1 2 3 4 5 6. Next it goes by 2's. 2 4 6 8. Finally it goes by 's. 6 9, next would be 12, 15.
1 goes into 7 and 5 and 8 and 9 and 6
LCM(4, 6, 9) = 36.
abs(4 - 9) * 6 - 6 or, equivalently, (9 - 4)*6 - 6
