The ratio of two quantities with different units, expressed as a rate per unit.
Ratios: Ratios are the comparison of two quantities. Unit rate is the ratio that refers to one unit. For example, 2 miles per hour means 2 miles traveled in one hour.
Fractions: Fractions can help understand how to divide the numerator by the denominator to find a unit rate.
Proportions: Proportions are an equation that shows that two ratios are equivalent. Unit rates can be found by setting up proportions and solving for the unknown.
Decimals: Unit rate can be shown in decimal form. For example, 0.5 meters per second means half a meter is traveled in one second.
Percents: Percentages can be used to show how much of one thing relates to another. Unit rates can be shown as percentages to compare products sold by different companies.
U.S. Customary Units: U.S. customary units of measurement such as inches, feet, and yards, can be used to find unit rates. For example, if you need to know how many miles you can travel on one gallon of gas, you would need to know how many miles are in a gallon.
Metric Units: The metric system is used around the world and includes units such as meters, grams, and liters. Metric units of measurement can be used to find unit rates for distance, weight, and volume.
Word problems: Often, unit rates are used in word problems. Solving unit rate problems in word problems requires you to understand how the units of measurement relate to the problem.
Graphs: Unit rates can be shown on graphs to compare data. Graphs can help show how different economy sectors contribute towards GDP, how different brands of products perform, or how different brands of cars perform.
Unit conversion: Converting units of measurement can help you evaluate a unit rate. For example, if you are comparing gas mileage for two vehicles with different units of measurement, you would need to convert the units to compare them.
Speed rate: It refers to the distance traveled by an object in a given amount of time. It is typically expressed in miles per hour or kilometers per hour.
Price rate: It refers to the cost of a product or service per unit. It is typically expressed in dollars per unit or cents per unit.
Density rate: It refers to the amount of mass per unit of volume. It is typically expressed in grams per liter or kilograms per cubic meter.
Interest rate: It refers to the cost of borrowing money. It is typically expressed as a percentage of the principal amount.
Flow rate: It refers to the amount of a substance that flows through a specific area per unit of time. It is typically expressed in gallons per minute or liters per second.
Production rate: It refers to the amount of output produced per unit of time. It is typically expressed in units per hour or pieces per day.
Exchange rate: It refers to the value of one currency in relation to another currency. It is typically expressed as the value of one unit of currency in terms of the other currency.
Consumption rate: It refers to the amount of a resource consumed per unit of time. It is typically expressed in gallons per hour or kilowatt-hours per day.
Failure rate: It refers to the frequency of failures in a particular system or component. It is typically expressed in failures per unit of time.
Error rate: It refers to the frequency of errors or mistakes in a particular process or system. It is typically expressed as a percentage of the total number of actions performed.
