Fractional Distances and Midpoints

The video tutorial covers the concept of fractional distance, starting with a review of the midpoint formula. It explains how to calculate fractional distances by finding midpoints and using rise over run. The tutorial includes examples of calculating fractional distances for different segments and provides practice problems for students to reinforce their understanding.
