A rate is a ratio that is used to compare different kinds of quantities.
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
Some common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc. In each case the first quantity is related to 1 unit of the second quantity.
For these ratios, it is usually very important to reduce to lowest terms, or even divide into a decimal so that the second quantity can be shown as a single unit (1).
