1. Definition: Unit rate is the ratio of two quantities, where one quantity is expressed as one unit. It is used to compare the cost or value of a single unit of one quantity to another.

2. Calculation: To calculate the unit rate, divide the total quantity by the total cost or value. For example, if you have 10 apples that cost \$5, the unit rate would be \$5/10 apples = \$0.50 per apple.

3. Application: Unit rate is commonly used in estimation to determine the cost or value of a single unit of a quantity. It allows for easy comparison between different quantities and helps in making informed decisions.

4. Importance: Unit rate helps in estimating costs accurately and efficiently. It is particularly useful in budgeting, pricing, and cost analysis.

5. Examples: Unit rate can be applied to various scenarios, such as calculating the cost per mile for gas, the price per ounce for groceries, or the rate per hour for services. It provides a standardized way to compare different quantities and make informed decisions.

Components of Unit Rate in Estimation:

1. Determine the Given Ratio:
- Identify the given relationship between two quantities, expressed as a ratio, fraction, or percentage.

2. Convert to Unit Rate:
- Divide the larger quantity by the smaller quantity to obtain the unit rate. This represents the value of one unit of the dependent variable for each unit of the independent variable.

3. Estimate Actual Values:
- Multiply the unit rate by the desired number of units to estimate the actual value of the dependent variable.

4. Use Proportional Reasoning:
- If the ratio is not given directly, use proportional reasoning to set up an equation and solve for the unit rate.

5. Apply Estimation Techniques:
- Use rounding and approximation to simplify calculations and estimate values.
- Make reasonable assumptions and apply common sense when necessary.

Example:

Given: A car travels 300 miles in 5 hours.
Unit Rate: 300 miles ÷ 5 hours = 60 miles per hour
Estimation: If the car wants to travel 240 miles, estimate the travel time:
240 miles ÷ 60 miles per hour = 4 hours
