Determining Unit Rates Using Pictures

This video tutorial explains how to determine unit rates using visual aids. It begins with an introduction to unit rates, providing examples and vocabulary. The lesson then demonstrates how to calculate the unit rate of wood flooring installed per hour by a carpenter. The process involves using multiples of fractions to find equivalent rates. The tutorial also reverses the calculation to determine the time required to install one square yard of flooring. The lesson concludes by simplifying the unit rates and summarizing the key points learned.

What is a unit rate?

• A type of fraction

• A comparison of a quantity to one of another quantity

• A comparison of two different quantities

• A measurement of time

How much wood flooring can the carpenter install in one hour?

• 4 square yards

• 3 square yards

• 2 square yards

What is the equivalent rate of wood flooring per hour if the carpenter works at 2/3 square yards per 1/6 hour?

• 3 square yards per hour

• 4 square yards per hour

• 5 square yards per hour

• 6 square yards per hour

How many hours does it take to install one square yard of wood flooring?

• 1/4 hour

• 1/2 hour

• 1/3 hour

• 1/5 hour

What is the simplified unit rate of time per square yard of wood flooring?

• 1/5 hour

• 1/4 hour

• 1/2 hour

• 1/3 hour

Which of the following is NOT a way to express a unit rate?

• Using the word 'to'

• Using a colon
