How to determine the ratio of a reduction dilation

The video tutorial explains how to determine a ratio by comparing lengths. It begins with an introduction to ratios and the concept of reduction, followed by counting lengths to create a ratio. The tutorial then demonstrates calculating the ratio from A to B, finalizing with an understanding that B is half the size of A. The process involves finding side lengths, creating a ratio, and ensuring accuracy in calculations.

What is the primary goal when determining the transformation from point A to point B?

• To determine the ratio of sizes

• To find the color difference

• To calculate the distance

• To identify the shape

When counting the lengths of segments, what is the length of segment A?

• 4

• 7

• 5

• 6

What is the length of segment B as counted in the video?

• 5

• 4

• 3

• 2

How is the ratio of B to A expressed after reduction?

• 1/4

• 1/3

• 1/2

• 1/5

What does the final ratio indicate about the size of B compared to A?

• B is twice the size of A

• B is one-third the size of A

• B is half the size of A

• B is the same size as A
