Subtracting Fractions With Equal Denominators

The video tutorial uses a scenario where Lisa's mother makes an apple pie and shares it with Lisa and her friends to teach the concept of subtracting fractions with equal denominators. Initially, the pie is divided into eight equal parts, and fractions are used to represent the portions taken and left. As more friends arrive, the tutorial demonstrates how to subtract fractions to find out how much pie remains. The lesson concludes with a summary of the subtraction process, emphasizing the importance of keeping the denominator constant while subtracting the numerators.
