Your rotation ratio is 33.333 / 11.6666 = 100 / 35
So the number of teeth ratio is 35 / 100
So the circumference of the discs should be in the ratio of 35 / 100
The diameters should also be in that ratio, say 3.5" and 10 " , or 7" and 20", etc.
Or if you are using a belt, the pulley diameters would be in the ratio 35:100 with a half-twist in the belt.
