ratio that compares 2 quantities measured in diiferent units
rate
A rate.
Rate
If you have two items using different units of measurement, you must first convert to the same type in to percentage. Then, you can compare the ratio, It is called coefficient of variability. For example if you want to compare length with weight of two variables or populations, then first convert the measurements in percentage and then go for comparision.
RATE!
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".

Rate
Time
It is a ratio.
what is it
There is the meter, that measures distance. There is the kilogram, which measures mass. There is the candela, which measures luminous intensity. There is the second, which measures time. There is the mole, which measures amount of substance. There is the Kelvin, which measures temperature. And there is the ampere, which measures electrical current. All other SI units are called Derived Units. Read more in the related link below.
None. Mechanical advantage is a ratio of two measures each of which has the same units and so it is a unit-less number.
True.
These are two different units of measurement. A cup measures volume and a gram measures weight.
