That's a rate, or more commonly, a ratio.
To compare to different units of measurement or a ratio that compares two quantities of different units (Ex: A car goes 100 miles in 1.5 hours, what is the rate)
[Directly] proportional quantities.
A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.
Proportional
Rate is a comparison based on division.
Imagine you have 20 objects at a cost of $90. Then the unit rate (the cost of one object) will be found by division. here $90 ÷ 20 = $4.50 (the unit price)
