Multiplication as Resizing (Part 1)

The video tutorial explains the concept of scaling, using a rope as an example. It introduces the idea of a scale factor, which is a ratio that determines how much an object is resized. A scale factor greater than one enlarges the object, while a scale factor of one keeps it the same size. A scale factor less than one reduces the object's size. The tutorial provides examples and calculations to illustrate these concepts.

What is the term used to describe the process of resizing an object?

• Translating

• Rotating

• Scaling

• Reflecting

If a rope is originally 6 feet long and is resized to 12 feet, what is the scale factor used?

• 3

• 1/2

• 2

• 1

What happens to the size of an object when a scale factor of 1 is applied?

• It remains the same

• It doubles in size

• It triples in size

• It halves in size

How is a scale factor represented when comparing the new size to the original size?

• As a difference

• As a ratio

• As a product

• As a sum

What is the result of applying a scale factor of 1/2 to a 6-foot rope?

• 9 feet

• 12 feet

• 3 feet

• 6 feet
