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 first step in determining the ratio from A to B?

How do you identify whether you are enlarging or reducing A to get to B?

What lengths were counted for A and B in the discussion?

What is the final ratio of B to A as determined in the text?

What is the significance of finding side lengths in creating a ratio?
