Conversions and Proportional Relationships

The video tutorial covers unit 2, lesson 5, focusing on understanding proportional relationships through various examples. It begins with identifying patterns in missing figures, followed by converting meters to centimeters using proportionality. The lesson then explores the relationship between time and water flow in a cooler, and calculates shrimp feeding requirements. Finally, it reviews homework problems to reinforce the concepts learned.

• A U-shaped pattern

• A zigzag pattern

• A linear increase

• A circular pattern

How do you convert meters to centimeters?

• Divide by 100

• Divide by 10

• Multiply by 100

In the water flow problem, what does the rate of 1.6 gallons per minute represent?

• The number of coolers filled per hour

• The time it takes to fill the cooler

• The amount of water flowing per minute
