Ratio
The result of dividing one number or expression by another. Sometimes
a ratio is written as a proportion, such as 3:2 (three to two).
More often, though, ratios are simplified according to the standard
rules for simplifying fractions or rational
expressions.
Note: The word "rational" indicates that a ratio (in
the second sense) is involved. The word rate also indicates a
ratio is involved, as in instantaneous
rate of change or average
rate of change.
