How to Multiply Fractions with Different Signs

This video tutorial explains how to multiply fractions with different signs. It begins by reviewing the concept of positive and negative signs in fractions. The tutorial outlines three rules for multiplying fractions based on their signs: if both fractions have the same sign, the product is positive; if they have different signs, the product is negative; and if one term is zero, the product is zero. The video provides examples, including multiplying two fractions with different signs and a more complex problem involving three fractions. It concludes with a demonstration of cross cancelling to simplify multiplication.

What is the result of multiplying -5/6 by 1/4, and why is the product negative?

Describe the process of cross-canceling when multiplying fractions, using the example of 1/8 and 4/5.
