________is a ratio comparing two quantities with different kinds of units
V125BC [204]

Answer:

Rate

Step-by-step explanation:

Rate is basically also a ratio. but it is the comparing of two different quantities with different units.

As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.

for example:

When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.

20 meters : 15 seconds

thus the lowest form of this relationship will be:

4 meters : 3 seconds

when i write it in Decimal form it becomes :

Ans : 1.33 meters/second   (Distance per unit time)

As this ratio have remaining units thus it is referred to as "RATE".
