Gear ratio's

Hi,bit of an odd one this,but one for the mathematically competent.
Most of us have read the Webster tuning manual,a great source of information,but i cant for the life of me work out how to calculate the % rise from 3rd gear to 4th gear as he does in his gearing charts.
These days there are more gearsets available,so i would like to be able to calculate the jump between gears.
Im thinking in particular of the Vijay Mk 2 gearbox that uses the Li150 3rd and the SX200 4th.
Hopefully there is a mathematician out there that doesnt have to use his fingers,then his toes to count!
