Subtraction of Fractions: Creating Like Denominators

This video tutorial teaches how to solve word problems involving the subtraction of fractions with unlike denominators by creating like denominators. It uses models to visualize fractions and explains common mistakes to avoid. Two example problems are solved: one involving a cat's food and another with a coffee pot, demonstrating the process of finding common denominators and subtracting fractions.

What is the initial amount of coffee in the coffee pot?

How much coffee does the Smith family drink?
