What does the word 'ratio' indicate in math?

• A. A ratio compares two quantities.
• B. A ratio is a sum of two quantities.
• C. A ratio is the product of two quantities.
• D. A ratio is a single quantity.

Answer: (A)

A ratio expresses a relationship by comparing two quantities. It shows how large one quantity is relative to the other, like 2:3, meaning for every 2 of one thing there are 3 of the other. It can also be written as a fraction (2/3) or read as “2 to 3.” This is different from a sum (which adds the amounts), a product (which multiplies them), or a single quantity (which is just one amount). For example, in a recipe with 2 cups of flour and 3 cups of milk, the ratio of flour to milk is 2:3, indicating the proportional relationship between the two ingredients.
