A rate compares two quantities that have different units of measure. Suppose a 2-liter bottle of soda costs $1.98. When the comparison is to one unit, the rate is called a unit rate. Divide both terms by the second term to find the unit rate. When the prices of two or more items are compared, the item with the lowest unit rate is the best deal. rate = price number of liters _____________ $ liters ________ = $1.98 for 2 liters unit rate = $ _____ $1.98 ÷ 2 2 ÷ 2 ________ = $0.99 for 1 liter = $ _____
