A **rate** is a type of ratio where something of one unit is compared with something else of another unit. Rates are applied in many real-world scenarios like unit conversions, speed/velocity, and per-item price.

Unit cancellation is a common strategy used in rate and conversion problems where if there are two instances of a unit written -- one on the numerator and the other on the denominator, then the instances are crossed out. For instance .
