Unit Analysis
Build Grade 9 math skills with Unit Analysis. Learn key concepts, work through practice problems, and apply algebraic thinking to solve equations and real-world problems.
Key Concepts
Property A unit ratio, or conversion factor, compares two measures that name the same amount. Since a unit ratio is equal to 1, multiplying it by a measure changes the unit but not the amount.
Examples Convert 5 miles to yards: $5 \text{ mi} \cdot \frac{1760 \text{ yd}}{1 \text{ mi}} = 8800 \text{ yd}$.
Convert 4000 meters to kilometers: $4000 \text{ m} \cdot \frac{1 \text{ km}}{1000 \text{ m}} = 4 \text{ km}$.
