Solve Word Problems by Doing Dilations

This video tutorial teaches how to solve word problems involving dilations using various scale factors. It covers the concept of dilation, where a preimage is transformed into an image using a scale factor and a center of dilation. Examples include enlarging a play ticket and comparing the dimensions of a tennis court and a table tennis table to determine if one is a dilation of the other. The tutorial also includes a problem involving a photographic enlarger, demonstrating how to calculate the necessary adjustments for proper dilation.
