The video tutorial explains how to multiply fractions using visual aids and develops an algorithm for faster calculations. It starts with a visual example of multiplying one-half by three-fourths, leading to the result of three-eighths. The tutorial then introduces an algorithm that involves multiplying numerators and denominators separately. This method is applied to another example involving a bake sale, demonstrating its effectiveness. Finally, the algorithm is generalized for any fractions, providing a reliable method for fraction multiplication.
