🔑 Key Concepts
- A unit rate compares a quantity to exactly 1 unit.
- To find a unit rate, divide the first quantity by the second quantity.
- Unit rates appear in shopping, speed, earnings, recipes, school situations, and conversions.
- Some unit rates are whole numbers or decimals, while others may be fractions.
💡 Main Idea
A unit rate answers the question “How much for 1?” Whether students are finding price per ounce, miles per hour, dollars per hour, or a measurement conversion, the goal is to rewrite the rate so the denominator is 1 unit.
✏️ Worked Examples
🧠 Math Vocabulary
- Rate: A comparison of two quantities with different units.
- Unit Rate: A rate that compares a quantity to exactly 1 unit.
- Equivalent Rates: Rates that represent the same relationship using different numbers.
- Unit Price: The cost for one item, one ounce, one pound, or another single unit.
- Conversion Rate: A rate that compares equivalent measurements in different units.
- Per: A word that means “for each” or “for one.”
📐 Unit Rate Rule
To find a unit rate, divide the first quantity by the second quantity.
\(\text{Unit Rate}=\frac{\text{first quantity}}{\text{second quantity}}\)
A unit rate can be written as an equivalent rate with a denominator of 1.
\(\frac{a}{b}=\frac{x}{1}\)
The value of \(x\) tells how much there is for one unit.
📚 What You Should Already Know
Students should know how to divide whole numbers and decimals, understand ratios and rates, and recognize that equivalent rates represent the same relationship.
🚀 What Comes Next
After finding unit rates, students can compare prices, analyze constant rates of change, solve proportional relationships, and work with fractional unit rates in seventh grade.
