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.

What is the main task Hank has been hired to do?

• Repair all the rooms in a hotel

• Clean all the rooms in a hotel

• Decorate all the rooms in a hotel

• Paint all the rooms in a hotel

How many hours does it take Hank to paint 3 hotel rooms?

• 12 hours

• 5 hours

• 7.5 hours

• 10 hours

What is the calculated time for Hank to paint 6 hotel rooms?

• 18 hours

• 15 hours

• 12 hours

• 10 hours

What is the unit rate for Hank painting one hotel room?

• 4 hours

• 3 hours

• 2.5 hours

• 1 hour

How is the unit rate used to write an equation for painting rooms?

• By dividing the unit rate by the number of rooms

• By subtracting the unit rate from the number of rooms

• By adding the unit rate to the number of rooms

• By multiplying the unit rate by the number of rooms

What is the equation derived to find the number of hours needed to paint any number of rooms?

• H = 3R

• H = 2.5R

• H = 2R

• H = 1.5R

What is the purpose of using the cross product property in this context?

• To simplify the equation

• To verify the equation

• To complicate the equation

• To ignore the equation

What is the total number of rooms Hank can paint in 1200 hours?

• 480 rooms

• 520 rooms

• 500 rooms

• 400 rooms

What mathematical operation is used to find the number of rooms in the hotel?

• Addition

• Subtraction

• Multiplication

• Division

What is the first step in solving for the number of rooms using the equation?

• Subtract 2.5 from both sides

• Divide both sides by 2.5

• Add 2.5 to both sides

• Multiply both sides by 2.5
