Name: ____________________ Math 8 Date: _____________ Unit 3 – Ratio, Rate & Proportional Reasoning Lesson 3.2: Rates In this lesson, I will learn to represent rates in a variety of ways identify, describe, and record rates used in real life use rates to analyze situations and solve problems Recall that a ___________________ compares two quantities measured in the same units. A __________________ compares two quantities measured in different units. A rate can be expressed as a __________________ that include two different units. Example: ______________________________________________ Fastest man on earth: 10.44m/s, or 10.44 meters per second, or Fastest car in the world: 470 Km/hr or 470 Kilometer per hour or To determine unit rates: Example1: a) Twelve notebooks cost $16.68. Find the unit rate. b) A 28oz can of tomatoes cost $1.96. A 16 oz can of tomatoes cost $1.26. Find the better buy. Example2: Determine the unit rate in each situation. a) Brandon runs 150 m in 25 s. b) Kira earns $88 for working 8 h. c) Cat food costs $9 for five cans.
