Understanding Rectangular Fraction Models

This video tutorial covers the subtraction of unlike fractions using rectangular fraction models. The instructor guides through two examples: subtracting 1/2 from 1/7 and subtracting 3/5 from 1/2. Each example involves drawing models, partitioning them to find common denominators, and performing the subtraction. The tutorial emphasizes simplifying the results and provides a clear, visual approach to understanding fraction subtraction.
