Final answer:
Unit conversions and calculations are based on knowing the appropriate conversion factors, such as feet in a mile or ounces in a pound, to derive the correct amounts in varying units of measure.
Step-by-step explanation:
When approaching questions related to unit rates and unit conversions, it's important to use consistent units and conversion factors. For example, to find out how far Justin ran in feet when given miles, one must know there are 5280 feet in a mile.
Similarly, converting flour weight from pounds to ounces requires the knowledge that there are 16 ounces in a pound. It is essential to apply the correct conversion rates for tons to pounds, cups to ounces, quarts to pints, and quarts to gallons in order to accurately determine the unit conversions needed for each question.
