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.
The two-speed feature of a DC cordless drill is typically constructed using a gear mechanism that allows the user to switch between two different gear ratios. This is often achieved through a simple gear train where a high-speed setting uses a smaller gear ratio for faster rotation, while a low-speed setting utilizes a larger gear ratio for increased torque. A switch or lever is integrated into the drill's design, enabling the user to easily change between these settings. This dual-speed functionality enhances versatility, allowing the drill to handle various tasks efficiently.

The gear ratio is the number of teeth in the driven gear divided by the number of teeth in the drive gear.
The 1992 Mitsubishi 3000GT typically features a 5-speed manual transmission with gear ratios approximately as follows: 1st gear is about 3.09:1, 2nd gear is around 1.89:1, 3rd gear is approximately 1.29:1, 4th gear is about 0.97:1, and 5th gear is roughly 0.75:1. For the automatic transmission variant, the gear ratios may differ slightly. These ratios contribute to the vehicle's performance characteristics, balancing acceleration and fuel efficiency.
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.
Bicycle gear ratios determine how many times the rear wheel turns for each turn of the pedals. Lower gear ratios make it easier to pedal uphill, while higher gear ratios make it easier to pedal on flat terrain or downhill. Gears work by changing the size of the chainrings and cogs, allowing the rider to adjust the resistance when pedaling.

Gear ratios are typically expressed as a fraction or a colon format, representing the relationship between the number of teeth on two gears. For example, if gear A has 20 teeth and gear B has 10 teeth, the gear ratio can be written as 20:10 or simplified to 2:1. This means that for every two rotations of gear A, gear B completes one rotation. Gear ratios can also be expressed in decimal form, such as 2.0, indicating the same relationship.
