This is an example of unit a rate. Essential Understanding You can write ratios and find unit rates to compare quantities. You can also convert units and rates to solve problems. Comparing Unit Rates Shopping You are shopping for T-shirts. Which store offers the best deal? Store A: $25 for 2 shirts Store B: $45 for 4 shirts Store C: $30 for 3 ...
When a rate compares a quantity to one unit of another quantity, the rate is a unit rate. The rate $15 _____ 3 T-shirts is not a unit rate because the rate compares the cost to more than one T-shirt. In a unit rate, the second quantity (or denominator) should be 1 unit. A speed limit is a unit rate. For example, the speed limit of 55 miles per ...
Lesson Objective: Students will learn how to compare two ratios and calculate unit rate using fractional amounts. Introduction: “Today we will find unit rate using complex fractions.”
A ratio compares two quantities in a given order. For example, if the number of oranges in a bag is twice that of the number of apples, this is a ratio of to 1 and is writen as: 2. 2 : 1. Each number is called a term of the ratio. The order in a ratio is important. The ratio of oranges to apples is 2 :1.
Ratios and Rates Worksheets. Both rates and ratios are comparisons of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit.
Example 1: Write the ratio that compares the number of footballs to the number of tennis balls. Example 2: Write the ratio that compares the girls to the total number of students.
