3.1.1 Understanding and using ratio notation

• What is a ratio used to show the relationship between quantities?

  Division
• The ratio 2:3 means there are 2 oranges for every 3 apples.

  False
• The antecedent is always the larger number in a ratio.

  False
• Match the term with its definition:

  Antecedent ↔️ First quantity being compared

  Consequent ↔️ Second quantity being compared against
• In what real-life scenarios is simplifying ratios useful?

  Recipes and product comparisons
• What is the ratio of boys to girls if there are 15 boys and 20 girls in a class?

  15:20
• What is the second step in simplifying a ratio after finding the GCF?

  Divide both parts by the GCF

  $\frac{15}{20}$
• What is the simplified form of the ratio 12:18 after dividing by its GCF?

  2:3
• What is the process of simplifying a ratio called?

  Reducing to lowest terms
• The ratio for mixing juice and soda is 1:3, meaning there is more juice than soda.

  False
• In the ratio 2:3, the number 2 represents the oranges.

  False
• Why does the order matter in a ratio?

  It reflects the relationship
