What are the two different ways that a ratio may be expressed?

• A. As a decimal and a percentage
• B. As a fraction and by placing a colon between the two numbers
• C. As a percentage and a whole number
• D. By adding and subtracting the two numbers

Answer: (B)

A ratio expresses the relationship between two quantities, showcasing how much of one number exists compared to another. One common way to represent a ratio is as a fraction, where the first number is the numerator and the second number is the denominator. For example, a ratio of 2 to 3 can be expressed mathematically as 2/3. Additionally, ratios can also be expressed using a colon between the two numbers, such as 2:3. This format clearly delineates the two quantities being compared, making it straightforward and easy to interpret. Both of these representations, as a fraction and using a colon, effectively communicate the same relationship between the numbers involved, thus making them the correct methods to express a ratio. The alternative options focus on formats that do not represent the fundamental characteristics of ratios themselves.
