Direct variation
The relation which one quantity or magnitude has to another of the same kind. It is expressed by the quotient of the division of the first by the second; thus, the ratio of 3 to 6 is expressed by / or /; of a to b by a/b; or (less commonly) the second term is made the dividend; as, a:b = b/a., Hence, fixed relation of number, quantity, or degree; rate; proportion; as, the ratio of representation in Congress.
The second term in the ratio is 1.
unit rate is a ratio between 2 measurements in which the second term is 1.

exchange rate
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
efficiency-------------- its not that. i have to say that it is " Productivity"
