Guided Notes
Key concepts students will learn:
- •
A proportion is formed by equal or equivalent ratios, meaning they represent the same comparison and relationship.
- •
To determine if two ratios form a proportion using equivalent fractions, first write the ratios in fractional form, then find the least common multiple between the bottom terms.
- •
If the equivalent ratios have the same value, then the original ratios are proportional; if the equivalent ratios are different, the original ratios are not proportional.
