Understanding Unit Rates and Costs

The video tutorial introduces sixth-grade students to the concept of unit rates, explaining that a unit rate is a ratio that compares a quantity to one unit of another quantity. The teacher provides three examples to illustrate how to calculate unit rates: determining the number of deer per square mile, calculating miles per gallon, and finding the cost per ounce. Each example involves setting up a ratio and performing division to find the unit rate. The tutorial emphasizes the importance of understanding equivalent ratios and using division to simplify them to a unit rate.

What does the term 'unit rate' refer to?

• A rate calculated for one unit

• A rate calculated for multiple units

• A rate that is always increasing

• A rate that is always decreasing
