Simplifying Ratios and Fractions

The video tutorial explains how to simplify ratios by converting them into fractions and reducing them to their simplest form. It covers three examples: simplifying 12 to 18, 1.2 to 0.2, and 1.5 to 2. The process involves identifying the highest common factor for whole numbers and using multiplication to eliminate decimals or fractions. The tutorial emphasizes the importance of expressing ratios in their simplest form for clarity and ease of understanding.
