How to Find & Use Unit Rate | 7.RP.A.1

The video tutorial covers finding and using unit rates, writing equivalent ratios, and using the cross product property to form equations. It includes a practical example of calculating the time required for painting hotel rooms at a constant rate. The tutorial is divided into four parts: calculating time for 6 rooms, determining the unit rate for one room, writing an equation for any number of rooms, and calculating the total number of rooms painted in a given time.

How many hours will it take Hank to paint 6 hotel rooms?

How do you set up equivalent ratios to solve for unknowns in a proportion?

What is the unit rate for Hank to paint one hotel room?

Write an equation that can be used to find the number of hours it will take Hank to paint hotel rooms.

What is the relationship between the number of hours and the number of rooms Hank can paint?

Describe the cross product property and how it applies to this problem.

How can you verify your answer when calculating the number of hours needed to paint a certain number of rooms?

How many total hours will it take Hank to paint all the hotel rooms?

Explain how you would determine the total number of rooms in the hotel if it takes Hank 1200 hours to paint them.

What steps would you take to solve for the number of rooms if given the total hours?
