Answer:
(change in output)/(change in input)
Step-by-step explanation:
A "rate of change" is usually computed as the ratio of a change in the output of a function divided by the corresponding change in the function's input. This is naturally a ratio, a fraction.
The rate of change of a graph is often described as "rise" over "run", so the fraction is ...
rise/run
In other cases, the "rate of change" or "unit rate" is the ratio of one value to another. For example, "miles per gallon" is found by dividing miles by the corresponding number of gallons. Similarly, "dollars per pound" is found by dividing dollar cost by the corresponding number of pounds. These are naturally fractions, and may be reduced in the usual way fractions are reduced.
