Navigating Negative Fraction Operations

In this video, Tiffany explains how to handle operations with negative fractions. She covers the necessary skills for adding, subtracting, multiplying, and dividing both fractions and integers. The video includes four examples: adding negative fractions, subtracting negative fractions, multiplying fractions without negatives, and dividing negative fractions. Each example is broken down into steps, emphasizing the importance of common denominators and treating numerators as separate integer problems. The video concludes with a reminder to apply regular fraction rules when no negatives are present.
