Understanding Fraction Multiplication and Simplification

The video tutorial explains how to find the product of three fractions, focusing on determining the sign of the product and simplifying the result. It begins by identifying the sign based on the number of negative factors, then demonstrates how to simplify fractions by removing common factors. The tutorial also introduces an alternative method using prime factorization to simplify fractions, ensuring the product is in its simplest form. The final result is a negative fraction, and the video provides a clear step-by-step explanation of the process.
