Scaled Copies and Basic Equations

The video tutorial covers the concept of scaled copies, using figures and real-world examples like the Rose Bowl Stadium. It explains how to identify scaled copies by comparing dimensions and proportions. The tutorial also includes a discussion on Tyler's reasoning about scaled copies and concludes with solving equations using multiplication, demonstrating how to find unknown values by completing equations.

Which figure is a scaled copy of the original 'A' if the original is 2 units tall and 2 units wide?

• A figure that is 1 unit tall and 1 unit wide

• A figure that is not symmetrical

• A figure that is 4 units tall and 4 units wide

• A figure that is 3 units tall and 2 units wide

Why is figure 3 not considered a scaled copy of the original 'A'?

• It is taller than the original

• It is not symmetrical like the original

• It is smaller in both dimensions

• It is wider than the original

What is the flaw in Tyler's reasoning about figure B being a scaled copy of figure A?

• Figure B is not half as wide as figure A

• Figure B is larger in both dimensions

• Figure B is taller than figure A

• Figure B is not symmetrical

Which picture of the Rose Bowl Stadium is a scaled copy of the original?

• Picture D, which is shorter in both height and width by the same percentage

• Picture C, which is shorter in height but wider in width

• Picture B, which has the same height but a much shorter length

• Picture A, which is slightly shorter in both height and width

Why is picture C not a scaled copy of the original Rose Bowl Stadium picture?

• Its height is shorter but its width is much wider

• Its width is the same as the original

• Its height is the same as the original

• Its dimensions are both smaller

What is the simplified form of 3 divided by 12?

• 1/5

• 1/3

• 1/2

• 1/4
