They weren't 'invented' - a gear ratio is simply the difference in the number of teeth on two connected gear wheels.
Gears were invented to make working easier.
When you are driving there are gears that you can switch to.Hope this helps. :)Prior to replacement I consider the possibility of changing the gear ratios: could you use a higher gear?If the 4th gear ratio is too low ( high number ) then it will limit the speed the scooter can achieve.If you need a lower gear ratio the hub allows you to fit a larger rear sprocket, and vise versa.These also work. :)
Gear ratios will let the engine run at the speed and load at which it is most efficient, which is good for low fuel consumption and an exhaust that is as clean as possible.
Jacques Cousteau is credited for and I believe invented the modern SCUBA gear for diving, making diving a sport accessible to many.
Nobody knows. There were gears thousands of years ago.
Reduction ratios: 1st gear 2.45:1 2nd gear 1.45:1 3rd gear 1:1 Overdrive 0.69:1 Reverse 2.22.1
The gear ratio is the number of teeth in the driven gear divided by the number of teeth in the drive gear.
Yes, they often are. Gear ratios and anatomical ratios are usually expressed in decimal numbers in relation to one.
Depends on the engine at what it's cruised at, revolutions per mile of the tires, transmission gear ratios, and rear end gear ratios.

There is no way to change gear ratios.
High gear ratios, 273,373,340 Low ratios, any thing starting with the #4 and up is a low gear ratio. 410 411 456 488 556 and up.

If you're talking about gear ratios, that would be a 1:1 ratio.
From page 46 of a 1966 Volkswagen Owners Manual, the gear ratios are: 1st gear 3.80:1 2nd gear 2.06: 1 3rd gear 1.26:1 4th gear 0.89:1 Reverse 3.88: 1
