Which term describes a comparison of two quantities by division, a colon, or the word 'to'?

• A. Ratio
• B. Rate
• C. Proportion
• D. Prime number

Answer: (A)

A ratio describes a comparison of two quantities by division, and it can be written as a fraction, a colon, or the word “to.” It shows how many parts of one quantity there are compared to the other. For example, the ratio of cats to dogs could be written as 3:2 or 3/2, meaning 3 cats for every 2 dogs. A rate, on the other hand, adds a per-unit context (such as miles per hour). A proportion is an equation stating that two ratios are equal (like 3:4 = 6:8). A prime number is a standalone whole number greater than 1 with no positive divisors other than 1 and itself.
